Summer 2017 | “The most common feedback from the workshop participants noted the increase in transparency within the EMC and NOAA at large, the increasing effort to engage the entire community, and the general sense of positive momentum of the community coming together to embrace the opportunity to use NGGPS as a foundation to build a true community modeling resource for the Nation.”

Winter 2017 | “These metrics can provide very succinct information about many aspects of forecast performance without having to resort to complicated, computationally expensive techniques. ”

Summer 2017 | The Developmental Testbed Center (DTC) was established in 2003 with a mission to facilitate research to operation transitions in regional Numerical Weather Prediction (NWP). The DTC fulfills this mission by (i) providing community support for regional operational systems, (ii) performing testing and evaluation of NWP innovations for possible operational implementation, and (iii) promoting interaction and collaboration between research and operational NWP communities through special workshops, visitor programs, and the… Read More

Winter 2017 | As the new Director of the Environmental Modeling Center (EMC), I have the pleasure of leading nearly two hundred world-class scientists, engineers and other staff in developing, transitioning, improving and maintaining a suite of global and regional environmental models to support the National Weather Service (NWS) mission of the protecting life and property for our country.  To meet the challenges of this mission, EMC has formed strategic partnerships with numerous community organizations over the years to… Read More

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… Read More

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… Read More

Summer 2017 | Post-processing is an essential but often overlooked component of numerical weather prediction and encompasses a broad range of concepts, methods, and tools to make raw model output more useful. The Unified Post Processor (UPP) can compute a variety of diagnostic fields, interpolate to pressure levels or specified (pre-defined or custom) grids, and de-stagger grids. Examples of the products include: T, Z, humidity, wind, cloud water, cloud ice, rain, and snow on isobaric levels SLP,… Read More

Winter 2017 | The community Hurricane Weather Research and Forecasting (HWRF) modeling system was upgraded to version 3.8a on November 21, 2016.  This release includes all components of the HWRF system: scripts, data preprocessing, vortex initialization, data assimilation, atmospheric and ocean models, coupler, postprocessor, and vortex tracker.  In addition to default operational features, the release includes capabilities to perform idealized tropical cyclone simulations run with alternate physics, and backwards compatibility for… Read More
