I downloaded the file and was able to open it with sdfopen without any problems. Based on these clues:

Open Error:  Data file type invalid
 --> The invalid description file record is:
 --> DTYPE hdfsds

Attempt to use feature that was not turned on when netCDF was built.

I believe the problem lies in your particular GrADS build, especially the hdf library. Can you send the output from 'q config'?
