Director's Corner: The Age of EPIC: What does this mean for DTC?

Gretchen Mullendore

Winter 2021 | In 2017, Congress instructed NOAA to establish the Earth Prediction Innovation Center (EPIC) to advance “observational, computing, and modeling capabilities to support substantial improvement in weather forecasting and prediction of high impact weather events.”  What will the details of EPIC look like?  EPIC has not yet been formed, so the community doesn’t know, and it’s not yet clear that NOAA knows either.  Hopefully, it can achieve its goal to improve accessibility to the operational code and data so that scientists… Read More

Who's Who: Tatiana Burek

Winter 2021 | Many of you may know Tatiana Burek as the developer and gatekeeper of METviewer, the visualization software for the verification package developed and supported by the DTC, but her life took a series of turns to arrive at the DTC. She grew up in Leningrad, Russia where she spent her childhood as a passionate competitor, both as a speed skater and swimmer, all while attending rigorous dance classes. Undaunted by year-round swim team practice sessions in the outdoor pool, whose coach… Read More

Community Connections: Building a Community through UFS Medium-Range Weather Application Users’ Training

Winter 2021 | The DTC, in cooperation with subject-matter experts from NOAA's Environmental Modeling Center (EMC) and Geophysical Fluid Dynamics Laboratory (GFDL), as well as NCAR’s Climate and Global Dynamics (CGD) Laboratory hosted a live, virtual training session for the Unified Forecast System (UFS) Medium-Range Weather (MRW) Application 4-6 November and… Read More

Did you know?: Data on the Cloud

Winter 2021 | NOAA’s Big Data Program (BDP) is providing public access to NOAA's open data on commercial cloud platforms through public-private partnerships with Amazon Web Services, Google Cloud Platform and Microsoft Azure. NOAA generates tens of terabytes of data a day from observations like satellites, radars, and buoys, and from weather models, and other sources. Did you know the available datasets include: UFS Coupled Model Prototype 5 (S2SP5), which is the latest experimental version of the UFS coupled atmosphere-ocean-sea ice… Read More

Lead Story: The Expanding METplus Community

Autumn 2020 | Verification and validation activities are critical to the success of modeling and prediction efforts ongoing at organizations around the world.  Having reproducible results via a consistent framework is equally important for model developers and users alike.  The Model Evaluation Tools (MET) was developed over a decade ago by the Developmental Testbed Center (DTC) and expanded to the METplus framework with a view towards providing… Read More

Director's Corner: USAF Perspective on DTC’s role in meeting future challenges and opportunities

Mike Farrar, USAF

Autumn 2020 | The U.S. Air Force (USAF) partnership with the DTC has provided superb value to the USAF over the years, as this collaboration dates back as far as 2003.  Early in the relationship, the DTC benefited the USAF-NCAR partnership with WRF development and transition to USAF operations.  In recent years, the DTC has focused primarily on USAF needs for model evaluation through continued development of the Model Evaluation Tools (MET), along with project efforts related to model testing and evaluation (T&E).  Throughout this… Read More
