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

Lead Story: NOAA and NCAR partner on new modeling framework
NCAR and NOAA MOA
Spring 2019 | NCAR and NOAA are each adopting a unified approach to coupled environmental modeling, where success for both efforts is critically dependent on community contributions. At the end of January 2019, NCAR and NOAA signed a Memorandum of Agreement (MOA) to develop a shared infrastructure that encourages the broader community to engage in improving the Nation’s weather and climate modeling capabilities. Collaborating on the development of a common infrastructure will reduce duplication of effort and create common community… Read More
Director's Corner: The Operational FV3 Era
Clark Evans
Spring 2019 | We stand at the dawn of the operational FV3 era, representing the first step in the implementation of NOAA's Next-Generation Global Prediction System (NGGPS). With this new era comes many challenges, but also many opportunities to work collaboratively to improve the operational modeling system. How can NOAA best work with the community to leverage these opportunities and develop a truly world-class weather and climate prediction system? A few ideas: Develop a decadal vision for world-class numerical weather prediction.… Read More
Who's Who: Gerard Ketefian
Spring 2019 | Gerard Ketefian tries to “get big computers to tell him if it’s going to be sunny or rainy or snowy tomorrow, and the next day, and the day after that, and…” that’s how he explains his job to a child - and he has two -- a 2-year old boy and 4-year old girl. Gerard’s background is engineering. He has a B.S. in civil and mechanical engineering and M.S. in environmental engineering with emphasis on environmental fluid mechanics (both air and water). Gerard’s Ph.D. involved computational fluid dynamics applied to atmospheric… Read More
Visitors: Forecast Skill of the High-Resolution Rapid Refresh (HRRR) Model for Banded Snowfall Events
Visitor: Jacob Radford
Spring 2019 | Jacob Radford, a Ph.D. student at North Carolina State University and visitor to the DTC during June of 2018, investigated the forecast skill of the High-Resolution Rapid Refresh (HRRR) model for banded snowfall events. In particular, he evaluated the HRRR’s ability to capture the location, areal extent, orientation, and aspect ratio of these locally enhanced regions of reflectivity. In theory, snowbands should be adequately resolved by the HRRR thanks to its fine grid-spacing, but model skill has not yet been assessed… Read More
Community Connections: Model Evaluation for Research Innovation Transition (MERIT)
Spring 2019 | The Model Evaluation for Research Innovation Transition (MERIT) project provides a critical framework for physics developers to test innovations within their schemes using selected meteorological cases that have been analyzed in depth. Comparing their results to baseline MERIT simulations will allow developers to determine whether their innovations address model shortcomings and improve operational numerical weather prediction. For the DTC’s AOP 2018, three high-impact global FV3 baseline cases were selected for in-… Read More
