Lead Story: An Overview of the Earth Prediction Innovation Center (EPIC)

Autumn 2019 | The Earth Prediction Innovation Center, or “EPIC,” will advance Earth system modeling skills, reclaim and maintain international leadership in Earth system prediction, and improve the transition of research to operations (R2O) and operations to research (O2R) within NOAA by working closely with partners across the weather enterprise.  EPIC’s legislative language is included as an amendment to the Weather Research and Forecasting Innovation Act (WRFIA) of 2017 (Public Law 115-25)… Read More

Director's Corner: A NOAA-NCAR Collaboration Toward Unified Modeling

Autumn 2019 | What does unified modeling mean to you? Perhaps an obvious meaning is that “unified” implies one single model: one choice for dynamics, physics, data assimilation, and postprocessing. Everyone uses the same code: universities, private companies, research labs, and operational prediction centers. It is a grand vision. As a community, we are not there yet. I argue that there is a more practical, and potentially more useful definition of unified modeling: codes are easily shared and interoperable. Why do I say this? At first… Read More

Who's Who: Kate Fossell

Autumn 2019 | Tell us a little about yourself and your career path. I’m a Wisconsin native and grew up fascinated by severe storms. Naturally, when it came time to think about college, I looked for meteorology programs in the midwest. I settled on Saint Louis University for my B.S. in Atmospheric Sciences and then earned my M.S. in Mathematics from the University of Wisconsin - Milwaukee (UWM).  After graduation, I stayed on at UWM as a researcher while also working for a UWM-affiliated meteorological consulting company called… Read More

Visitors: Using Machine Learning to Post-Process Ensemble-based Precipitation Forecasts

Autumn 2019 | Ensembles are useful forecast tools because they account for uncertainties in initial conditions, lateral boundary conditions, and/or model physics, and they provide probabilistic information to users. However, many ensembles suffer from under-dispersion, sub-optimal reliability, and systematic biases. Machine learning (ML) can help remedy these shortcomings by post-processing raw ensemble output. Conceptually, ML identifies (nonlinear and linear) patterns in… Read More

Community Connections: Container & CCPP AMS Short Courses

Autumn 2019 | One of the primary goals of the DTC is to provide software and infrastructure that aid in transitions between the research and operational communities.  The American Meteorology Society (AMS) provides an ideal venue for sharing these tools with the community through the AMS short course offerings at the Annual Meeting.  The DTC is looking forward to presenting two short courses at the 100th AMS Annual Meeting in Boston, MA in January 2020.  “Integrating Numerical Weather Prediction (NWP) System Components… Read More

Did you know?: METplus

Autumn 2019 |   The Model Evaluation Tools (MET) were developed and released to the community by the Developmental Testbed Center more than a decade ago.  At that time, the tools included computation of traditional statistics for continuous fields (temperature, pressure, and height) and dichotomous fields (precipitation, clouds, fog, and high impact events). MET also included a spatial verification method, using objects, which complemented traditional statistics.   Over the past five years, new flexibility and… Read More

Software Release: Announcing UPP V4.0.1 Bug Fix Release

2019-08-21 | Dear UPP Community, The Developmental Testbed Center (DTC) is pleased to announce the release of the Unified Post Processor Bug Fix Version 4.0.1. Significant bug fixes include: FV3GFS processing fix: Modified input format for processing FV3GFS data. Users should use UPPV4.0.1 for all FV3GFS processing. Previous versions are now considered legacy for FV3GFS. Users should use 'binarynemsiompiio' instead of 'binarynemsio' in their run script. The binarynemsio format option will not be supported in the future. Scripts in this… Read More
