CHANGES

The precipitation assimilation algorthim in the EDAS has been modified to be less aggressive by eliminating the addition /creation of latent heat and moisture fields. Details can be found at http://www.emc.ncep.noaa.gov/mmb/ylin/newpptasm/

Modifications to the PBL physics were added at 00Z 7/16/2004, see change log for details.

Modifications to the Noah LSM physics were added at 12Z 7/27/2004, see change log for details.

Assimilation of NEXRAD level 2.5 radial wind data added 12Z 9/20/2004
