Hi All:

When processing WRF_CHEM 4.2.2 for the test Sahara Dust Case, we are seeing two Unlimited dimensions in our wrfout file. This is causing access problems such as the example below using ncdump.

Code:
% ncdump -h http://kyrill.ias.sdsmt.edu:8080/thredds/dodsC/CLASS_Examples/AES_744_Area/STUDENTS/wjc/chem_tutorial_1/wrfout_d01_2010-07-14_00.nc.html
ncdump: http://kyrill.ias.sdsmt.edu:8080/thredds/dodsC/CLASS_Examples/AES_744_Area/STUDENTS/wjc/chem_tutorial_1/wrfout_d01_2010-07-14_00.nc.html: http://kyrill.ias.sdsmt.edu:8080/thredds/dodsC/CLASS_Examples/AES_744_Area/STUDENTS/wjc/chem_tutorial_1/wrfout_d01_2010-07-14_00.nc.html: NetCDF: file not found

The link to the file is found here: http://kyrill.ias.sdsmt.edu:8080/th...c/chem_tutorial_1/wrfout_d01_2010-07-14_00.nc

Under CDMRemote in the TDS services, you can see the variable list and the "other" unlimited value:

Code:
netcdf CLASS_Examples/AES_744_Area/STUDENTS/wjc/chem_tutorial_1/wrfout_d01_2010-07-14_00.nc {
  dimensions:
    Time = UNLIMITED;   // (49 currently)
    DateStrLen = 19;
    west_east = 40;
    south_north = 40;
    bottom_top = 39;
    bio_emissions_dimension_stag = UNLIMITED;   // (0 currently)
    bottom_top_stag = 40;
    soil_layers_stag = 4;
    west_east_stag = 41;
    south_north_stag = 41;
    seed_dim_stag = 12;
    
    ...

And is associated with one variable in the file that we can see:

Code:
    float DRY_DEP_LEN(Time=49, bio_emissions_dimension_stag=0, south_north=40, west_east=40);
      :FieldType = 104; // int
      :MemoryOrder = "XYZ";
      :description = "dry deposition velocity";
      :units = "cm/s";
      :stagger = "Z";
      :coordinates = "XLONG XLAT XTIME";
      :_ChunkSizes = 1U, 1U, 20U, 20U; // uint

If anyone has any ideas, help here would be appreciated.

Cheers and Thanks
