CHANGES

LAND-SURFACE PHYSICS CHANGES

The percent of frozen precipitation computed by the Eta microphysics is now passed to the land-surface model (so-called "Lackmann" change)

PRECIP ASSIMILATION CHANGES

Details on the precipitation analysis adjustment can be found at http://www.emc.ncep.noaa.gov/mmb/ylin/pcpinflat12/.

3DVAR CHANGES

The Eta 3DVAR code was modified to assimilate radiances from the GOES-12 satellite
