Robb..

Thanks very much for your prompt attention to our difficulties
transforming GRIB files to netCDF.  Your message gives me
considerable hope that all is now well and that we will be able to
proceed to take advantage of the many capabilities of netCDF.

I am looking forward to hearing from Ben that the decoding is
proceeding as efficiently as we had hoped.

Best regards, John
