G-EDAS for NU-WRF released

The Goddard Ensemble Data Assimilation System for NU-WRF (G-EDAS for NU-WRF) was released on 11 October 2016.  This supports and includes NU-WRF Version 8 Patch 2 ("Bjerknes Patch 2").

 

G-EDAS consists of three major components:

(1) A forecast model (NU-WRF);

(2) Observation forward models extracted from the Gridpoint Statistical Interpolation System (GSI) and the Goddard Satellite Data Simulation Unit (G-SDSU); and

(3) The Maximum Likelihood Ensemble Filter (MLEF).

 

G-EDAS supports both conventional and satellite observations, including microwave radiances under cloudy and precipitating conditions.  The system has been run successfully on the NASA Pleiades and Discover supercomputers and should be portable to other platforms.

 

The NU-WRF Software Usage Agreement also covers release of the G-EDAS (since NU-WRF is included in the package).
 

See the System Specifications document for more information.
