MM5 Modeling System Version 3

Version 3 Nestdown Change Log

Changes in release-3-7:

Changes made in release-3-7


12/27/02:

Changes in release-3-6:

Changes made in release-3-6


Changes since release-3-5:

12/21/01:

  • Change gas constant from 287. to 287.04 to be consistent with it is used elsewhere in the modeling system programs.

    • Affected files:
      src/module_base_state.F, module_vert_interp.F


12/5/01:

Changes in release-3-5:

Changes made in release-3-5


11/6/00:

Changes in release-3-4:

Changes made in release-3-4


Changes since release-3-3:

6/7/00:

  • Simplify the way make is done. Now one needs only to type 'make' to compile on one's machine.

    • Affected files:
      Makefile, configure.rules, macros_pregrid, macros_regridder (new)
      src/Makefile

3/13/00:

  • Add compilation option for Linux using Portland Group Fortran 90 compiler.


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.

8/12/99:

  • Added OpenMP parallel directives.
