Who's Who: Evelyn Grell

Spring 2021 | Evelyn Grell’s story begins in a suburb of Philadelphia, PA where she was raised.  Her interest in weather was inspired from spending time with grandparents on the Jersey shore.  Her grandfather was an avid sailor and even built his own sailboat. Naturally, monitoring the weather and especially the wind direction was essential before setting sail.  Evelyn never seriously considered meteorology as a career… Read More

Bridges to Operations: Growing the WPC HydroMeteorological Testbed: Immersive Forecasting and New Perspectives

Spring 2021 | The Hydrometeorological Testbed at NOAA/NWS/NCEP Weather Prediction Center (WPC) is a naturalistic decision-making environment, a physical space, a collaboration space, and an insight-generating laboratory. We explore observations and models (Numerical Weather Prediction, Machine Learning and statistical models) in order to evaluate, validate and verify weather-forecasting procedures, tools, and techniques.  Read More

Community Connections: DTC Embarks on International Project to Provide Information about Model Physics Uncertainty

Spring 2021 | The “Model Uncertainty Model Intercomparison Project” (MUMIP) is an international effort to better understand model-physics uncertainty, and how to represent it in stochastic physical parameterizations. After all, physical parameterizations provide an approximate solution to physical processes occurring in… Read More

Did you know?: UFS Short-range Weather Application Version 1.0 has been released

Spring 2021 | The latest Unified Forecasting System (UFS) application to be released is the Short-Range Weather (SRW) Application, which targets predictions of atmospheric behavior on a limited spatial domain and on time scales from less than an hour out to several days. The SRW Application version 1.0 Read More

Director's Corner: Lisa Bengtsson

Spring 2021 |   My involvement in model physics development and coordination for operational use, in both Europe and the U.S., has afforded me an interesting and rewarding perspective on the unique philosophies and approaches taken along the path of research to operations on both sides of the Atlantic. In many ways, the challenges faced by large organizations or collaborative consortiums when developing/selecting physics for operations are very similar for Europe and the U.S. For instance, when… Read More

Announcement: Announcing the CCPP and SCM v5.0.0 online tutorial

2021-04-22 | The Developmental Testbed Center is pleased to announce that an online tutorial is now available for the Common Community Physics Package (CCPP) v5.0.0 and the CCPP Single Column Model (SCM) v5.0.0. The goal of this tutorial is to familiarize CCPP beginners with its key concepts: 1) how it is used within host models, 2) what makes a piece of code compatible with the CCPP, and 3) how collections of physics parameterizations are organized into suites. It includes lecture-like videos followed by hands-on exercises. The… Read More

Director's Corner: 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
