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

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

2020-12-10 | The Developmental Testbed Center (DTC) is pleased to announce the release of the METexpress application, Version 3.0.1 (dated Oct. 7, 2020).  METexpress is a simplified data analysis visualization component of the enhanced Model Evaluation Tools (METplus) verification system.     Download & Installation To download this version of METexpress… Read More

2020-10-06 | The UFS Medium-Range Application v1.1.0 was publicly released on 10/06/2020. This is a minor release of the system that predicts atmospheric behavior out to about two weeks. New capabilities in this release include the ability to ingest GFS raw initial conditions in netCDF format (to be introduced with GFSv16), flexibility to customize the post processor output, and safeguards against occasional extreme sea surface temperatures present in the initial conditions. This release is compatible with Python 3 and with recent… Read More

2020-10-05 | The Developmental Testbed Center is pleased to announce the Common Community Physics Package (CCPP) v4.1.0 public release on October 5, 2020. This release contains the three elements of the CCPP: the CCPP-Physics, a library of physical parameterizations, the CCPP-Framework, an infrastructure  that connects the physics to host models, and the CCPP Single Column Model, a simple host model that employs the CCPP-Physics and CCPP-Framework. A complete list of capabilities associated with the CCPP v4 series can be found here.… Read More

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

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
