[ncl-talk] hdf file to netcdf

[Vanúcia Schumacher]

Hi NCL team

I would like to convert data in hdf to netcdf.
I tried to use ncl_convert2nc, but it did not work:

Classic mode NetCDf does not support unsigned integer types: LST will be written as type short
Classic mode NetCDf does not support unsigned integer types: QC will be written as type short
Classic mode NetCDf does not support unsigned integer types: Error_LST will be written as type byte
Classic mode NetCDf does not support unsigned integer types: Emis_31 will be written as type byte
Classic mode NetCDf does not support unsigned integer types: Emis_32 will be written as type byte
Classic mode NetCDf does not support unsigned integer types: View_angle will be written as type byte
Classic mode NetCDf does not support unsigned integer types: View_time will be written as type byte

I also tried this and it did not work (data attached):

   fils = ("MOD11_L2.hdf")
      f = addfile(fils, "r")
    var = short2flt_hdf(f->LST)
             printVarSummary(var)
var!0   = "lat"
var!1   = "lon"
...
