Out of curiosity, why do you think there will not be a large need in the future for this. Most of the meteorological community tries to conform to the GRIB standard.
Kevin, Most of the raw data is initial converted to GRIB and then transported to remote sites where it is decoded into netCDF, or display package formats ie. gempak, etc. Not the other way around. The initial conversion of LAPS to netCDF is an exception to the rule.
On another note, I had a question about the buoy2nc decoder. Why does it deal with buoys and C-MAN but not include ships and drifting buoys????????
The buoy decoder was written using the WMO manual on codes No. 306. The CMAN's are not included and use a different format. Actually they use the synoptic format, that includes station data input file. So the synoptic decoder could be modified to process CMANs. If you send me some raw CMAN reports, I could modify the synoptic decoder for CMANs. At this time, I'm busy so it would probably be a couple weeks before I get a chance to look at it. Also the synoptic station table would have to be updated with the CMAN entries. I don't know why CMANs are not in the codes book and why they use a non-standard bulletin header. Robb...
