Did you know?: NOAA TESTBEDS & THE DTC

Winter 2014 | During California field exercises of the Hydrometeorological Testbed (HMT), a key objective has been to improve longer-range forecasts of so-called “atmospheric rivers” or ARs (narrow streams of mid- to low-level moisture) and other meteorological patterns that produce very heavy rainfall. During efforts to evaluate model forecasts for these exercises the DTC has explored methods that can provide more meaningful verification than standard scores. One such method represents regions of, say, precipitation… Read More

Summer 2013 | Through its Visitor Program, the DTC is currently working with Adam Clark, a scientist at the Cooperative Institute for Mesoscale Meteorological Studies (CIMMS), on a project that involves using the Method for Object-based Diagnostic Evaluation – Time Domain (MODE-TD) for identification, tracking, and visualization of simulated supercells in high-resolution models, which will be applied and tested during annual NOAA/Hazardous Weather Testbed Spring Forecasting Experiments.

Did you know?: NOAA TESTBEDS & THE DTC

Spring 2013 | For several winter seasons, the DTC has worked with the Hydrometeorology Testbed (HMT) to develop effective verification techniques for ensemble forecasts of heavy winter precipitation associated with atmospheric rivers in California. For example, the performance diagram below displays the impact of model resolution. See additional HMT information and links on the DTC website. See http://www.dtcenter. org/eval/hmt/2012/.

Lead Story: “Building a Weather-Ready Nation by Transitioning Academic Research to NOAA Operations” Workshop

Spring 2018 | The “Building a Weather-Ready Nation by Transitioning Academic Research to NOAA Operations” Workshop was held at the NOAA Center for Weather and Climate Prediction in College Park, Maryland, on November 1-2, 2017. NOAA and UCAR organized the meeting that drew more than one hundred participants from universities, government laboratories, operational centers, and the private sector. Members of the organizing committee included Reza Khanbilvardi, City College of New York, Chandra Kondragunta, NOAA/OAR, Jennifer Mahoney,… Read More

Spring 2016 | During the next decade, the Air Force will be working with our national and international modeling partners toward a goal of consolidated capabilities

Lead Story: Expanding Capability of DTC Verification

Winter 2016 | Robust testing and evaluation of research innovations is a critical component of the Research-to-Operations (R2O) process and is performed for NCEP by the Developmental Testbed Center (DTC). At the foundation of the DTC testing and evaluation (T&E) system is the Model Evaluation Tools (MET), which is also supported to the community through the DTC. The verification team within the DTC has been working closely with DTC teams as well as the research and operational communities (e.g. NOAA HIWPP program and NCEP/EMC… Read More

Lead Story: NITE: NWP Information Technology Environment

Summer 2015 | Over the years, the DTC has put in place several mechanisms to facilitate the use of operational models by the general community, mostly by supporting operational codes (for data assimilation, forecasting, postprocessing etc.) and organizing workshops and tutorials. By stimulating the use of operational codes by the research community, composed of universities, NCAR, and government laboratories, several new NWP developments have been transitioned to NCEP operations. However, in spite of the… Read More

Lead Story: DTC: The Next Ten Years

Winter 2015 | The transition of research advances into operations (abbreviated as R2O), particularly those operations involving numerical weather prediction, satellite meteorology, and severe weather forecasting, has always been a major challenge for the atmospheric science community. With a preeminent mission to facilitate R2O in mind, NOAA and NCAR established the DTC in 2003. Since then, the DTC has worked toward this goal in three specific ways:  by providing community support for operational NWP systems, by performing… Read More

Lead Story: SREF and the Impact of Resolution and Physics Changes

Autumn 2013 | As operational centers move inexorably toward ensemble-based probabilistic forecasting, the role of the DTC as a bridge between research and operations has expanded to include testing and evaluation of ensemble forecasting systems. In 2010 the ensemble task area in the DTC was designed with the ultimate goal of providing an environment in which extensive testing and evaluation of ensemble-related techniques developed by the NWP community could be conducted. Because these results should be immediately relevant… Read More

Director's Corner: Director’s Corner - Georg Grell

Spring 2018 | As chief of the Model Development Branch (MDB) at NOAA’s Global System Division (GSD), I am honored to work with many of the scientists from the DTC. The DTC has been a vital partner for the development, testing, and evaluation of the Rapid Refresh (RAP) and High-Resolution Rapid Refresh (HRRR) models, and I look forward to continuing this valuable collaboration as the community works together to define and develop the next-generation modeling system.  The work performed in my branch at GSD is strongly linked to the five… Read More

Director's Corner: Ralph Stoffler

Spring 2016 | Ralph Stoffler, a member of the US government Senior Executive Service, is the USAF Director of Weather, and the USAF Deputy Chief of Staff for Operations. In this capacity, he is responsible for the development of weather and space environmental doctrine, policies, plans, programs, and standards in support of Army and Air Force operations. He is responsible for overseeing and advocating for Air Force weather resources and monitors the execution of the weather program. He is the functional manager for 4… Read More

Director's Corner: Barb Brown

Winter 2015 | The DTC was established a number of years ago to facilitate the transition of new capabilities in weather forecasting from research to operations (R2O), with a focus on the WRF model. Over the years, many things have changed – for example, the DTC now works with multiple sets of code (WRF, GSI, MET, HWRF, and so on) which will soon include global prediction systems – but that fundamental mission remains the same. The DTC accomplishes its goals through strong connections to the operational and research… Read More

Director's Corner: Greetings from the Heartland!

Autumn 2013 | The Air Force Weather Agency (AFWA) has long been a partner with the DTC since its “unofficial” early days of “core testing” (remember those), to its official charter membership signing in September of 2009, to date. Air Force Weather (AFW) recognized early, the essential role this organization could, and would, play in bolstering and mitigating an ever-growing US Air Force resource constrained terrestrial weather RDT&E environment. Further partnering with our NOAA National Centers for Environmental… Read More
