NU-WRF Version 9 patch 2  (v9p2-wrf391-lis72 - hot fix) ("Charney") was released on 1 February 2019.

WHAT CHANGED:

• Fixed a problem observed in LIS precipitation being consistently less than that coming from WRF and which was due to a unit conversion issue. This bug may impact some results, specifically soil moisture and overall soils wet/dryness, for very long simulations.
• This release also contains several build system enhancements that had already been merged into the develop branch.

NU-WRF Version 9 (v9-wrf391-lis72) ("Charney") was released on 13 December 2017.

WHAT CHANGED:

NU-WRF Version 8 Patch 4 (v8p4-wrf371-lis71rp8) ("Bjerknes Patch 4") was released on 3 March 2017.

WHAT CHANGED:

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).
