Guoqing Ge on Trail Ridge Road

“Read ten thousand books and travel ten thousand miles.”  – A Chinese proverb and a favorite quote of Guoqing Ge who loves to read, would choose the superpower ability to fly, and has an ambitious travel bucket list that includes the North or South Pole and the Amazon rainforest. He has already traveled far from his hometown of Anqing China, an 800-year old city on the shores of the Yangtze River. Anqing is a 4-hour high-speed train ride to Shanghai, and almost 7,000 miles from Longmont, Colorado, where he moved with his wife and son in 2015.

Guoqing earned his Bachelor’s degree in Meteorology from Nanjing University in China, and a Master’s from Peking University. His Ph.D. on convective-scale data assimilation is from the University of Oklahoma, where he stayed on as a post-doc for a few years before joining GSD/CIRES as a research scientist in August 2015.

In July 2017, Guoqing joined the Data Assimilation task of the DTC. His role is to provide community user support for NOAA operational data assimilation system - Global Statistical Interpolation (GSI) and Ensemble Kalman Filter (EnKF) - and to conduct testing and evaluation of emerging data assimilation techniques. He says the best thing about his job is being well-connected with the data assimilation community and moving the latest research results into operations to make forecasts better.

Colorado’s beautiful mountain views, amazing weather and clouds, and outdoor activities inspired Guoqing to lose more than 30 pounds. He stays healthy by skiing, running, hiking, watching NBA games, and playing with his 10-year old son who likes many of the same things -- reading too. The most important thing he has learned is to take notes wherever possible, just as a Chinese Proverb says “the palest ink is better than the best memory.”

Grant Firl

Spring 2018

The long and winding path to becoming an atmospheric scientist began at a young age for Grant, like many atmospheric scientists. He split his childhood years between watching occasional storms develop over the Sandia Mountains of Albuquerque, NM and the frequent passing of MCSs (Mesoscale Convective Systems) and derechos over the forested hills of southwest Missouri.

Grant credits his interest in science and math to a string of inspirational teachers from elementary school and onward, but his focus on meteorology was born of a shared interest in the discipline with his dad who obtained a B.S. in meteorology in the late 1970s. In college, his interests shifted from severe weather to atmospheric modeling and he majored in mathematics and minored in computer science in preparation for graduate studies. He obtained his M.S. and Ph.D. in atmospheric science under David Randall's tutelage at Colorado State University, primarily developing parameterizations for the convective planetary boundary layer using advanced techniques for predicting subgrid-scale variability.

After a postdoc appointment for studying machine-learning algorithms for improving planetary boundary layer parameterization methods, Grant was hired as a Project Scientist I at NCAR to work on the Global Model Test Bed (GMTB) project in the fall of 2015. He now serves as the Node Activity Coordinator for this project. For the past two years, Grant has worked with the GMTB team to design and implement a Common Community Physics Package and an Interoperable Physics Driver. The team is also building a testing platform to experiment with promising physical parameterization advances and to provide this shared capability to the broader community. Grant has thoroughly enjoyed his time working in the DTC and claims that his favorite aspect of the job is the "problem solving" aspect and the opportunity to work with and learn from an array of like-minded, driven, and brilliant people.


Grant Firl

Grant married his wife, Julia, in 2009 and has a 5-year old son (Wesley) and 3-year old daughter (Evelyn) who keep him on his toes when he is out of the office. After a brief hiatus from frequent backpacking/hiking trips when his kids were very young, Grant is looking forward to returning to the mountains with regularity and sharing the unique landscape and wildlife with his family. Other hobbies closer to civilization include playing softball with the venerable "Hailraisers" team in Boulder and the "Cyclones" team in Fort Collins and tinkering with various woodworking and automotive repair projects.

Evan Kalina

Autumn 2017

Evan knew he wanted to be a meteorologist when he was five years old -- every type of thunderstorm that blew through Kendall, FL enamored him. When Joe Cione, a hurricane researcher moved in across the street, his future career was sealed.

After graduating in 2010 from Florida State University with a B.S. in meteorology, Evan moved to Boulder for graduate school at the University of Colorado, where he analyzed model simulations and radar data from supercell thunderstorms. Cione serendipitously moved to Boulder about the time Evan graduated with his Ph.D. and invited Evan to do a postdoc. In that role he used similar techniques to the ones he used to study supercells and applied them to hurricanes. During his postdoc, he also became interested in writing and managing code efficiently. Joining the DTC has been a great opportunity to use and refine those skills further.

Evan currently works for the NOAA Earth System Research Laboratory Global Systems Division as the Node Activity Coordinator for the DTC Hurricane Task. His primary duty is to coordinate model development activities for the Hurricane Weather Research and Forecast (HWRF) system. He makes sure that model developers have access to the latest version of the HWRF code that runs operationally at NCEP, and that they can work within the HWRF code repository. This coordination helps transition innovations that improve the model forecast into operations. "It's satisfying to be on the cutting edge of numerical weather prediction," says Evan, "and to contribute to an operational system that is essential for protecting lives and property from hazardous weather."



Evan enjoys the physical and mental challenges of the Colorado mountains and spends most of his spare time outdoors. He likes to run, bike ride, hike, and backcountry camp. He is slowly ticking off the Fourteeners – his favorites so far have been Longs, Pikes, and Crestone Needle. About a superpower he wishes he had: "The pack that I take hiking would be a lot lighter if I didn’t have to eat or drink…"

Evan's life highlights include seeing seven tornadoes while storm chasing in southeast Colorado the day he graduated with his Ph.D., flying through Hurricane Matthew on the NOAA P-3, and traveling to Iceland in the spring of 2015.


Man Zhang

Winter 2017

As a visiting scientist at the University of Maryland in 2005, Man Zhang learned of Colorado’s reputation of being a great place to live. When her husband had an opportunity to come to Colorado as a visiting Ph.D. student, they didn’t think twice about moving. They love Colorado and have been in the Boulder area for almost 10 years.

Man was a post-doc at CIRA in the ensemble data assimilation group. She applied the hybrid variational-ensemble data assimilation system (HVEDAS) developed at CIRA to the NOAA operational Hurricane Weather Research and Forecasting (HWRF) modeling system to directly assimilate satellite observations in the tropical cyclone inner core. She also demonstrated the potential impacts of cloud-affected satellite radiances on the tropical cyclone inner-core region analyses and forecasts. “What I like most is learning new things,” Man says, “models are always evolving.”

Man joined NOAA/GSD/CIRES in July 2013 to support Nonhydrostatic Icosahedral Model (NIM) development. Since March 2016, Man has worked with the Global Model Test Bed (GMTB) to create software reference documentation on the Global Forecast System (GFS) physics suite (using Doxygen) to provide technical information to scientists and developers. She also works closely with physics developers at GMTB to modify the parameters that they want to experiment with in GFS-NOAA Earth Modeling System (NEMS). Recently, she has been running GFS-NEMS with the Grell-Freitas cumulus scheme. “It is interesting to think about the science behind tunable parameters,” she says.

Man is thankful her brother and his family, and her parents live close - all relocating to Colorado from the Hubei Province in Central China. Her 8 year old daughter and 3 year old son keep her busy with piano, dancing, and indoor climbing classes. They like road trips as a family and have explored most of national parks in the West and some in the East, with Utah’s Arches National Park and the Great Smoky Mountains National Park being their favorites. Over the holidays they enjoyed time up in Steamboat to ski and relax in the hot springs.

Jamie Wolff

Summer 2017

I grew up in Mound, MN, which is a western suburb of the Twin Cities. While most would consider Minnesota a cold and snowy state, I apparently wanted colder and snowier weather because I decided to head further north to Grand Forks, ND to attend the University of North Dakota (UND). I am an avid UND hockey fan and love heading to the games when they come out to play University of Denver or Colorado College in Colorado. Experiencing bitterly cold temperatures walking to class at UND certainly made me appreciate the amazing weather we have here in Colorado! I do have one lasting piece of home - I love shoveling snow and will choose to do so knowing that most of the time around here it will melt in a day or two!

I graduated from UND in the spring of 2000 and started working in the Research Applications Laboratory (RAL) at NCAR a few weeks later; I feel very fortunate to still be here 17 years later! I have been involved with a lot of projects in RAL over that time, including aviation weather, road weather, and numerical weather prediction (NWP). For each of those tasks I have generally been involved with statistics and performance assessment of algorithms or models. Currently, I conduct NWP testing and evaluation within the Regional Ensemble and Global Model Test Bed groups in the DTC. I have learned a lot over the years working with some very distinguished researchers at NCAR and NOAA.

I went to UND in pursuit of an atmospheric sciences degree and in addition came away with a future husband, Cory, who also works at NCAR as a project manager for the National Science Foundation aircraft. We have one daughter who keeps us busy attending volleyball and choir/orchestra events. We love to travel around our beautiful state and beyond. The travel experience I treasure the most to-date is spending time in Sydney, Australia and seeing the Sydney Symphony Orchestra play at the iconic Opera House. This is what inspired my 4th grader at the time to start playing a string instrument! In my free time I love to knit, having just finished my first sweater, and generally like to be outside hiking, jogging, skiing, dabbling in photography, or looking for agates to polish.


Jamie Wolff conquered Colorado’s highest peak, Mount Elbert at 14,400 feet.

Chunhua Zhou

Spring 2016

Circumstances can make it hard to connect with people, and with snowstorms and parent-teacher conferences, catching up with Chunhua Zhou took a few tries. But meeting her and learning about her work in the DTC made the effort worthwhile.

Chunhua and her younger brother grew up in central China. While he still lives there and runs a small business, Chunhua went to the University of Hawaii in 2003, receiving her Ph.D. in Meteorology in 2009. Her thesis studies involved the dynamics of the tropical intraseasonal oscillation and its interaction with the synoptic variability. Before joining the DTC, she worked as a postdoc producing daily numerical weather predictions for Hawaii using the WRF model.

Chunhua has kept quite busy since moving the DTC, working in the Data Assimilation team under Hui Shao on GSI testing and evaluation (TNE) and also community supports. Besides GSI, she has also worked on other data assimilation systems such as WRFDA. As GSI evolved from 3DVAR, to 3D ensemble-variational GSI hybrid, to the 4D ensemble-variational hybrid method, Chunhua’s efforts also shifted from GSI 3DVAR for regional application, to 3D GSI hybrid for hurricane forecasts, to the testing and evaluation of the current new capability of 4D GSI hybrid. She is also working with Josh Hacker on cloudy radiance data assimilation studies.

Chunhua enjoys living in Colorado with her husband Shenghong – a civil engineer working in Denver – and her 9-year-old daughter Sonya and 5-year-old son Jason. Asked about possibly returning to China some day, Chunhua says only for visits, as she would like to stay where she is and keep doing the work she’s doing for some time to come. So you might see her out hiking the trails in the area with her family, if there are no snowstorms or school activities, at least.


Michelle Harrold

Winter 2016

Growing up in Chicago showed Michelle Harrold how to be an optimist. That happens while you wait for your favorite Cubs to finally win a World Series.

After completing her B.S. in Meteorology from Valparaiso, Michelle moved to Colorado State University for graduate work. She received her M.S. in Atmospheric Science in 2009. By the winter of 2010 she was working as a mesoscale modeler at UCAR. This year Michelle added to her tasks, making time to help with the Global Modeling Test Bed (GMTB).

In her spare time, Michelle loves to be outdoors, including hiking and camping, and skiing, although the latter caused a torn rotator cuff in her first year on the slopes. Michelle says she’d happily join the DTC skydiving club, should it ever start.

As if her DTC duties and active life away from work weren’t keeping Michelle busy enough, she was married in August and purchased a house this fall. And as a dog lover, she’s hoping to add a furry friend to the mix soon as well. Let’s hope Michelle’s active schedule needs to be interrupted next Fall while she roots for her hometown Cubs in the playoffs.

Hongli Jiang

Summer 2016

I liked how Hongli Jiang explained “scale-aware” physics parameterizations using her office and a printer as an example. She has always been excited about physics and atmospheric sciences, and wanted to make sure I understood the concept. If you have a large grid box the size of your office, the size of your printer is insignificant in that space. If the grid box is the size of your desk, the size of the printer now impacts that space, and you need to include the printer in your description of your desk. Hongli is from Tianjin, a large port city near Beijing.

Hongli has been a CIRA Research Scientist for 21 years. After working in the ESRL/Chemical Sciences Division with aerosol and cloud modeling, she wanted to change her focus to she has work with the real-time cloud-scale modeling on 0-3 hour time scales. Now she is working with longer time scales - out to 48 hours. Her role in the DTC is in the Global Modeling Testbed working with the NGGPS to test several suites of physics. Lately they have been test cases for 3 months in the winter and 3 months in the summer to use as a benchmark.

Away from the office, Hongli loves to be outdoors, and volunteers in Longmont’s “Clean-Up Green Up” campaign to make area parks, trails and open spaces more beautiful. She also likes to travel and experience the contrasts of different regions such as the Pacific Northwest rainforests compared with New York City - both are full of life, just different kinds. Indoors, she enjoys classical music and live productions--witnessing the Berlin Philharmonic in person was a dream-come-true.


Kathryn Newman

Autumn 2016

As a Junior Atmospheric Science major, at the University of North Dakota (UND), Kathryn Newman organized 25 weather labs for hundreds of aviation students that were required to take Meteorology (ATSC 110). The multi-tasking and organizational skills she developed come in handy as the DTC Hurricane Task Lead to oversee transitioning Hurricane Task research to EMC. “It’s challenging to keep track of all the moving parts in modeling research and getting them into operations,” she says, “But it is cool to be involved at this level--to know what goes into the models.” She also serves on the Model Evaluation Team and the Data Assimilation Team.

Kathryn has been with NCAR since 2009. She led the development of a functionally-similar operational environment for the Air Force Weather Agency to determine an appropriate initial configuration for their impending Gridpoint Statistical Information data assimilation for operations.. She is proud to have wrapped that project up and the results published.

She earned her B.S. and M.S. from UND. Her Master’s work was ground validating satellite products for atmospheric radiation. She also worked on MM5 and WRF particle (aerosol?) dispersion applications for the Army High Performance Computing Research Center.

Kathryn grew up Anoka, Minnesota where she remembers trying to get her Halloween costume over her snowsuit. In college, she braved the cold with other students to stand in line to get the best seats. UND posted signs: “Stand at your own risk,” with a thermometer nearby for bragging rights. She and her husband road-trip to Omaha, Colorado Springs, or even Minneapolis to catch college hockey games in their spare time.

Kathryn wanted to be a veterinarian when she was younger because she loved animals. Though life took her in a different direction, she likes to hike Chautauqua trails with Lucy, her beagle. She says she and her husband like to do typical “Colorado stuff;” ski, hike, and visit craft breweries. Avery Brewing Co. is currently at the top of her list.

Christina Holt

Summer 2016

A small town on the border of Alabama and Georgia produces an unusually high number of students that pursue careers in science. Ranburne, Alabama, population 300, is the hometown of Christina Holt. Christina credits Mr. Jason Cole, her high school physics teacher, for creating opportunities for his students to shine and pushing them to do their best. After high school, she went on to attend the University of South Alabama, and completed her graduate work at Texas A&M. Just a few days after defending her PhD in 2014, she began her career in modeling at ESRL/GSD.

Christina’s major role in the DTC has been to support the HWRF model. She loves to work on a team that pushes research advances into operations, while also pushing computational boundaries forward. “Weather gives immediate feedback,” she says, “so we can ultimately make the forecast better in actual operations in a matter of months.”  She works to keep lines of communications open with the end users at NCEP. Regular HWRF development meetings provide the opportunity to ask questions, learn about developers’ experiences and focus areas, and discuss the next steps.

Christina also serves as Chairperson of the CIRES Member’s Council; her goal is to build a strong connection between CIRES staff at DSRC and CIRES staff on campus.  She pushes herself to face her fears – from emceeing the CIRES Rendezvous for the first time in front of hundreds to people, to rock climbing - “Let’s try it!” Christina has made the most of living in Colorado by learning to ski, hike, and storm chase, and loves her dogs “Toots” (like “Tootsie Roll”) and “Roscoe.”

Her favorite book is “Isaac’s Storm,” about the 1900 Galveston Hurricane, but she also treasures her copy of “The Storm of the Century” by Al Roker about the same event. Her aunt and uncle chased down Mr. Roker on a recent national tour for an autographed copy – the only one he granted that day!

Jeff Beck

Summer 2015

Some people feel comfortable staying close to home, but Jeff Beck has been across the country and across the ocean, with more experience already than many people have in a lifetime.

Jeff received his B.S. in Meteorology from Penn State University, then moved on to Texas Tech to obtain his Master’s and Ph.D. in Atmospheric Science, completing his studies in 2009.

After a year working at a wind energy company in Austin, Texas, Jeff moved across the Atlantic, taking up a post-doctoral position at Meteo-France. “I knew some basic French at that point, and I thought it would be a good experience for me.”  The position lasted for three and a half years, when Jeff returned to the U.S. to work at NOAA’s Global Systems Division in September 2014.

Jeff quickly moved into duties with the Developmental Testbed Center. He is an integral part of the team that developed the NOAA Environmental Modeling System (NEMS) Nonhydrostatic Multiscale Model on the B-grid (NMMB) Tutorial that took place at the NCWPC in April 2015, taking on tasks ranging from managing the tutorial website and creating an NMMB User Guide, to testing the scripts and code for the tutorial’s practical session and helping with the practical on day 2 of the tutorial. Jeff is now the lead for the second NMMB tutorial coming in Spring 2016. Jeff also works on the North America Rapid Refresh Ensemble (NARRE) physics package, developing a stochastic suite that will over time outperform the current mixed-physics suite.

When he’s not busy with all his work tasks, Jeff enjoys the outdoors of Colorado, and spends time skiing, hiking and running. So if you happen to meet Jeff on the trails around the Foothills, be sure to say “Bonjour!”


Ming Hu

Winter 2015

Ming is one of several DTC scientists with cross-Pacific ties, with early roots in central China (near Xian) and school and work experience in Jiangsu (where his parents live), the Nanjing Institute of Meteorology, Beijing, and the University of Oklahoma, where he earned his PhD in 2005. Since 2007 he has been working at ESRL/GSD in Boulder. One of the go-to people for data assimilation work at the DTC and at GSD with the RAP/HRRR, he is called upon not only for development work on data assimilation products and applications, but also for community GSI support and for help at tutorials and workshops. These teaching experiences are in fact high on his list of favorite activities. Although he enjoys a good relationship with developers at EMC, he admits to feeling a bit daunted when he compares the scope of the effort at GSD with the 30 or so scientists working on GSI at EMC. He and his family are clearly settled here in Boulder (his wife also works at GSD), but he does seem a bit nostalgic when he talks about the Yellow Mountains, maybe his favorite spot in China.


Laurie Carson

Summer 2014

When Laurie says “Well, this isn’t exactly rocket science,” we’d be well-advised to listen; she actually was a rocket scientist. After her physics degree at Iowa State, she worked as a scientific programmer at the aerospace divisions of General Dynamics and Martin Marietta on orbital mechanics and other satellite-related projects. The ups and downs of the defense industry eventually began to wear on her, and in 1992 she came to Boulder to work at NCAR, gradually moving into NWP activities. Laurie joined the DTC as a software engineer in 2008, and since then has been a go-to contributor for several projects that involve the NEMS modeling system from EMC, in particular the NMMB dynamic core now in active development. A focus of these efforts has been to port, configure and test a variety of model configurations on different computing platforms. Along the way she has worked with Jamie Wolff on NAM testing on the NCAR Yellowstone computing system, with Isidora Jankov on NARRE (North American Rapid Refresh Ensemble) related testing on NOAA’s Zeus computing system, and with Greg Thompson on microphysics/radiation coupling, also on the Yellowstone system. She has also been working with DTC and EMC staff to develop some basic user guides for the NEMS community. Given these efforts, it’s not surprising that she would judge her most valuable and enjoyable tasks to be those that contribute to community support, and that involve interaction at a working level with EMC and DTC colleagues.

Perhaps the requirements of a detail-demanding job at DTC do carry over, for better or worse, into non-work time; this would help to explain the interest in quilting suggested by the picture!


Tim Brown

Winter 2014

If you still harbor a notion that software engineers live narrow lives, a few minutes with Tim will quickly persuade you otherwise. Between his present 3-year stint with DTC’s hurricane task and graduate school in Perth, Australia, Tim has worked in Toronto with the Ontario Institute for Cancer Research; Australia with the Center for Water Research; Switzerland, the UK and Antarctica. He declines to speculate where his next career move might take him.

In Boulder, he has taken on a varied set of responsibilities, including teaching at recent DTC & EMC-sponsored Hurricane WRF tutorials and preparing numerical model documentation for HWRF. His most recent task, however, has been the collaboration with EMC in the conversion of the hurricane model scripts into Python, which he says will unify the operational and research communities thus enabling greater O2R and R2O. Outside of work, he greatly appreciates Colorado’s opportunities for backcountry skiing and bicycling. Perhaps that will help keep him in the DTC fold for a while!


Tara Jensen

Autumn 2014

An old management adage says that if you need some new task done NOW, ask someone who is already busy. Although she probably cringes to hear it, this applies well to Tara, with an exception: she would first offer to take it on. Her tireless approach to work follows pretty directly from a commitment to accept new challenges in new places. In practice, it has led to twists and turns along the way. After completing her Master’s degree at Colorado State University in aerosol/cloud interactions in marine stratus, her graduate work at Colorado State University was interrupted to act as a flight and support scientist in private industry, followed by taking part in every level (forecasting, modeling, data management, ground control, flight scientist and management) of weather modification field programs in the United Arab Emirates and Wyoming. Much of her field work was in airplanes (to which she credits having a strong stomach). Tara left NCAR briefly to participate in wind energy research in St. Paul, Minnesota but quickly returned to NCAR to join DTC with a focus on verification-related work (specifically with the MET package). She has been involved with extensive real-time and retrospective verification for the Hydrometeorological Testbed (HMT) and the Hazardous Weather Testbed (HWT), most recently as the verification task lead. Her most enjoyable DTC experience, she says, has been teaching at workshops and tutorials, and her work on HWT verification, particularly on interpreting results, has been especially satisfying. Keeping up with Tara’s work life is easy, since much of the verification-related activity at DTC (MET tutorials, workshops, AMS meetings, and prediction exercises) has her fingerprint on it. Keeping track of her outside-of-work life is a different story. She continues her busy lifestyle by participating in her nine-year-old daughter’s school activities, sports and other activities, all of which somehow seem to take on a life of their own!


John Halley Gotway

Spring 2013

If you’ve submitted a question to the MET help desk, or attended a MET tutorial, there’s a very good chance that you already know John Halley Gotway. John joined NCAR’s Research Applications Laboratory (RAL) as a software developer in 2004 and has been contributing to the verification efforts within RAL and the DTC. John’s background is in mathematics.

He worked in Los Angeles at Northrop Grumman, before NCAR and the Rockies drew him to Colorado. His expertise is in numerical verification techniques. In particular, his fingerprint is on much of the internal workings of the MET code. He has also played several roles in applying MET to many testing and evaluation projects.

Outside of work, John’s children, Otis (7), Robin (4), and Cate (1) keep him very busy. One thing you may not know is that besides computing expertise, John contributes directly to critical RAL protein intake by providing fresh eggs from his “gentlemen’s farm” near Longmont. Next time you call or email him with a C++ question, ask him how his chickens are doing.


Ligia Bernardet

Summer 2013

When a DTC pioneers’ plaque is eventually installed, Ligia’s name will be on it. She was involved with DTC activities even before it formally existed, assessing the feasibility of high resolution ensemble systems with Steve Koch. At the moment she is principally working on tropical storm forecast models as lead of the DTC Hurricane Task. For insider information about the new HWRF release and its assessment, she is the first call to make.

Ligia’s interest in meteorology and numerical modeling was first developed at the University of São Paulo, Brazil, where as an undergraduate she helped provide rainfall forecasts for the local television station and the state environmental agency. As she tells it, this was a trial by fire certainly, but also an eye-opening experience with the operational side of meteorology that stuck with her, and she credits these forecasts as preventing many deaths and injuries in urban regions where landslides pose a very serious risk. After PhD studies at Colorado State University and a subsequent postdoc in Boulder, she returned to Brazil and the operational arena for a 2-year stint on a tiger team that got a numerical modeling system going in the National Weather Service. Since her return to Boulder in 2003, she has worked at the DTC and at the Global Systems Division of ESRL on several numerical model, data assimilation, and forecast evaluation projects, including projects to choose the dynamic core of the Rapid Refresh model and to improve the air-sea fluxes in Hurricane WRF.

Ligia remembers Pedro Silva Dias, one of her undergraduate professors, saying that the relationship between research and operations, via R2O, should be a glass door with an equal dose of O2R, not a ‘valley of death’ as it can sometimes seem. After these early experiences with operations and then several twists and turns along research paths, she is often amazed to have come nearly full circle at the DTC.

Hui Shao

Autumn 2013

In many ways, Hui is the quintessential DTC lead. Stationed at NCEP’s Environmental Modeling Center but spending several weeks a year in Boulder, she lives R2O (data assimilation variety) day in and day out. Besides the frequent commutes, she is a long-distance veteran in another way, with undergraduate and masters’ level education in China, a PhD at Florida State, and now her dual appointment of sorts in DC and Boulder. There was some chance at Nanjing University that she would follow a different career: space science was her first choice but the availability of meteorology courses led her in that direction. She credits two events during her studies as important points in her career. A DA seminar in Nanjing impressed her with the ‘forward/backward’ mathematical beauty of adjoint formulations, and during her first year in Tallahassee regular meetings with a professor helped to bring out the ‘bigger picture’ of her dynamic meteorology courses.

At EMC and the DTC, Hui is most proud of helping to form a stronger and closer partnership between these two centers and creating a new pathway between operations and research communities. The collaboration between two centers has now been expanded beyond just data assimilation. Her vision of DA needs and requirements include a strong sense that better ways to handle extremes are needed, and she is a firm believer that effective DA can’t be just about data but must have a physical grounding as well. If anyone is well-placed to bring that vision into the R2O arena, it would be Hui.
