  src/Makefile

Changes in release-3-3 (1/26/00):

Allow NESTDOWN to work with MMINPUT file with masking fields. NESTDOWN is recommended to generate nest input files for MM5 if using OSU LSM model option.
Allow time period for processing to be less than a full day. Use less_than_24h = .TRUE. in record1 of namelist.input file.
Allow change of SST to land ice catagory if SST is cold enough. Use sst_to_ice_threshold = 'a temp value' in record2 of namelist.input file.
Allow multiple output times. Use ifdatim in record5.
Fix memory leak.
Fix a bug when interpolating vertical motion field, w. This could cause difference in generated files.

Changes in release-3-2 (9/27/99):

9/27/99:

Positive definite fields set to zero if < 1.e-10
This prevents very small or negative hydrometeo variables going into model's initial and boundary conditions.
Fixed masked interpolation for LSM
If the input to nestdown has LSM data, such as sea ice, and water equivalent depth of snow, Nestdown now will properly interpolate them across land-water boundary.
