Kevin Kelleher, NOAA GSD

Autumn 2014 | During my first 15 months as the ESRL Global Systems Division Director, I have learned about the DTC and its role in the modeling community. The DTC has made remarkable gains in supporting the WRF model within the community that has contributed to the great success and usage of the model both nationally and internationally. I believe the DTC is unique in how it is funded and operated as a joint effort between NCAR and NOAA, along with partners from the Air Force. It is my observation that there is a significant effort to… Read More

Who's Who: Kathryn Newman

Autumn 2016 | As a Junior Atmospheric Science major, at the University of North Dakota (UND), Kathryn Newman organized 25 weather labs for hundreds of aviation students that were required to take Meteorology (ATSC 110). The multi-tasking and organizational skills she developed come in handy as the DTC Hurricane Task Lead to oversee transitioning Hurricane Task research to EMC. “It’s challenging to keep track of all the moving parts in modeling research and getting them into operations,” she says, “But it is cool to be involved at this… Read More

Visitors: Harnessing the Power of Evolution for Weather Prediction

Visitor: Paul Roebber

Summer 2016 | As a DTC Visitor in 2015, Paul Roebber explored an idea for generating ensemble weather predictions known as evolutionary programming (EP). The method relies on a gradually and increasingly restrictive cost function to produce and to evaluate succeeding generations of a population of algorithms until such time as a best ensemble solution is determined based on cross-validation. The approach was developed by Roebber to produce baseline prediction equations equivalent to linear or nonlinear multiple regression… Read More

Did you know?: Did you know there are suggested topics for Visitor Projects that receive special consideration?

Autumn 2016 | Advance the forecast skill of the DTC-supported HWRF modeling system through improved physics and/or initialization Advance the analysis capability of the DTC-supported Gridpoint Statistical Interpolation and/or the NOAA Ensemble Kalman Filter (EnKF) Data Assimilation systems through development, testing, and evaluation of advanced data assimilation techniques and the addition of new data types or measurements Transition innovations in atmospheric physical parameterizations to NOAA’s Next-Generation Global… Read More

Release Date 10.04.2017

Autumn 2017 | The Developmental Testbed Center (DTC) is pleased to announce the release of the following community data assimilation systems: Version 3.6 of the Community Gridpoint Statistical Interpolation (GSI) data assimilation system Version 1.2 of the Community Ensemble Kalman Filter (EnKF) data assimilation system The released packages for GSI and EnKF and the documentation for each can be accessed through each system website as… Read More

Software Release: Release of the MET version 6.0 Verification Package

Software Releases

Summer 2017 | The MET development team at the DTC is pleased to announce the release of the MET version 6.0 verification package. It is available for download from the MET Users web page. The MET development team significantly enhanced the run-time performance of a number of tools, enhanced the data and file format capabilities, and added new capabilities for point observations, gridded analyses and tropical cyclone and probabilistic verification. Full details about the changes for this new… Read More

Lead Story: Community Modeling Workshop Outcome

Summer 2017 | “The most common feedback from the workshop participants noted the increase in transparency within the EMC and NOAA at large, the increasing effort to engage the entire community, and the general sense of positive momentum of the community coming together to embrace the opportunity to use NGGPS as a foundation to build a true community modeling resource for the Nation.”

Lead Story: Evaluation of New Cloud Verification Methods

Winter 2017 | “These metrics can provide very succinct information about many aspects of forecast performance without having to resort to complicated, computationally expensive techniques. ”

Director's Corner: Bill Kuo

Summer 2017 | The Developmental Testbed Center (DTC) was established in 2003 with a mission to facilitate research to operation transitions in regional Numerical Weather Prediction (NWP). The DTC fulfills this mission by (i) providing community support for regional operational systems, (ii) performing testing and evaluation of NWP innovations for possible operational implementation, and (iii) promoting interaction and collaboration between research and operational NWP communities through special workshops, visitor programs, and the… Read More

Director's Corner: Michael Farrar

Winter 2017 | As the new Director of the Environmental Modeling Center (EMC), I have the pleasure of leading nearly two hundred world-class scientists, engineers and other staff in developing, transitioning, improving and maintaining a suite of global and regional environmental models to support the National Weather Service (NWS) mission of the protecting life and property for our country.  To meet the challenges of this mission, EMC has formed strategic partnerships with numerous community organizations over the years to… Read More
