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/.

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

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

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

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

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

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
