[ncl-install] Fwd: HDF5 to NETCDF conversion

[Dennis Shea]

(2292)THX for sending the file.
--------------------------------
NCL 6.3.0 and the unreleased 6.3.1

I think the problem is that one of the dimensions has an illegal character.

   dimensions:
      DIM_000 = 1
      time = 1
      Latitude = 2816
      Longitude = 2805
      ^A = 2816                 <==========  illegal
      DIM_005 = 0
      DIM_006 = 0
   variables:
      integer GeoX ( Longitude )
         CLASS :        DIMENSION_SCALE
         REFERENCE_LIST :       <ARRAY of 0 elements>

      integer GeoY ( ^A )
         CLASS :        DIMENSION_SCALE
         REFERENCE_LIST :       <ARRAY of 0 elements>

      short Latitude ( ^A, Longitude )
         DIMENSION_LIST :       <ARRAY of 0 elements>
         _FillValue :   32767
         add_offset :    0
         long_name :    latitudeN_SCALE
         scale_factor : 0.01
         standard_name :        latitudeN_SCALE
         units :        degrees_northLE

      short Longitude ( ^A, Longitude )
         DIMENSION_LIST :       <ARRAY of 0 elements>
         _FillValue :   32767
         add_offset :    0
         long_name :    longitudeorthLE
         scale_factor : 0.01
         standard_name :        longitudeorthLE
         units :        degrees_easthLE

      float SST ( time, ^A, Longitude )
         DIMENSION_LIST :       <ARRAY of 0 elements>
         _FillValue :   -999
         coordinates :  time Latitude Longitude
         long_name :    Sea Surface Temperature
         standard_name :        Sea Surface Temperature
         units :        Kea Surface Temperature

I don't necessarily think this is an NCL issue. netCDF does not
recognize certain characters.


However, I have opened a JIRA ticket (2292). A core NCL developer is
going to look at this.

6.3.0 and the unreleased 6.3.1

ncl_filedump

have problems.

This is largely because the file you sent has characters not
recognized by netCDF / NCL
