Community Connections: 2018 DTC Community Unified Forecast System Test Plans and Metrics Workshop

Summer 2018 | The 2018 DTC Community Unified Forecast System Test Plan and Metrics Workshop was held at NOAA’s National Center for Weather and Climate Prediction (NCEP) on July 30 - August 1, 2018. The major goal of this workshop was to work towards a community test plan with common validation and verification metrics for the emerging Unified Forecast System (UFS). The plan will serve as a guide for the Numerical Weather Prediction (NWP) community for testing and evaluating new developments for the UFS models and components by… Read More

Lead Story: Keeping up with Model Testing & Evaluation Advances: New Verification Displays

Winter 2014 | As numerical model predictions and functions proliferate and move toward ever higher resolution, verification techniques and procedures must also advance and adapt.

Lead Story: THE 2013 HURRICANE WRF

Summer 2013 | As the 2013 hurricane season continues in the North Atlantic and eastern North Pacific basins, a newly minted HWRF model is providing forecasts for the National Hurricane Center (NHC) on a new machine and with significant code additions. On July 24, the operational HWRF went live on the Weather and Climate Operational Supercomputing System (WCOSS). A research version for testing continues in use on the jet computers at the NOAA ESRL Global Systems Division. New, more efficient code promises to provide… Read More

Lead Story: Mesoscale Model Evaluation Testbed

Spring 2013 | The DTC provides a common framework for researchers to demonstrate the merits of new developments through the Mesoscale Model Evaluation Testbed (MMET). Established in the Fall of 2012, MMET provides initialization and observation data sets for several case studies and week-long extended periods that can be used by the entire numerical weather prediction (NWP) community for testing and evaluation. The MMET data sets also include baseline results generated by the… Read More

Director's Corner: Bill Lapenta

Summer 2013 | Dear Colleagues, The end-to-end modeling systems in the NOAA operational numerical guidance suite are scientifically based, and research results must and do cross the “Valley of Death” into operations. However, the operational and research communities need to make this journey more efficient and cost effective. That’s one reason why we have testbeds like the DTC. During 20 years as a research scientist at NASA, I had the opportunity to work closely… Read More

Director's Corner: Welcome Message by Bill Kuo

Spring 2013 | Welcome to the first issue of a quarterly newsletter for the Developmental Testbed Center (DTC). The research to operations (R2O) transition in numerical weather prediction (NWP) is a major challenge facing the U.S. meteorological community. It has been recognized that the U.S. has the largest community around the world working on weather research and numerical modeling. Yet, most of these research results do not directly benefit operational NWP. The DTC was established in 2003 with a mission to… Read More

Who's Who: Tim Brown

Winter 2014 | If you still harbor a notion that software engineers live narrow lives, a few minutes with Tim will quickly persuade you otherwise. Between his present 3-year stint with DTC’s hurricane task and graduate school in Perth, Australia, Tim has worked in Toronto with the Ontario Institute for Cancer Research; Australia with the Center for Water Research; Switzerland, the UK and Antarctica. He declines to speculate where his next career move might take him. In Boulder,… Read More

Who's Who: John Halley Gotway

Spring 2013 | If you’ve submitted a question to the MET help desk, or attended a MET tutorial, there’s a very good chance that you already know John Halley Gotway. John joined NCAR’s Research Applications Laboratory (RAL) as a software developer in 2004 and has been contributing to the verification efforts within RAL and the DTC. John’s background is in mathematics. He worked in Los Angeles at Northrop Grumman, before NCAR and the Rockies drew him to Colorado. His expertise is… Read More

Bridges to Operations: Innovation in HWRF 2013 Baseline

Spring 2013 | One of the regional numerical weather prediction models used operationally by the National Weather Service is the Hurricane WRF (HWRF), a coupled model with atmospheric and ocean components that exchange fluxes of short- and long-wave radiation, momentum, moisture, and heat. The momentum flux is particularly important because the strong winds in tropical cyclones cause turbulence and upwelling in the ocean, which can lead to transport of cold water from deep in the ocean towards the surface, reducing… Read More
