19991011: May 3 case study



Kevin,

As Bob mentioned, the data is not SAO or metar, or other standard
format. It looks like wherever you got the data from, they keep
an ascii decode for some package. The data obviously has the
station ID, lat,lon,elev,hour,temp,dewpt etc parsed out. 
Since METAR and SAO reports do not have station lats/lons-
everyone has to merge that data in at some point. 

The data is not GEMPAK or McIDAS data- those are binary files. Nor
is it NetCDF or WXP. 

For your information, the data sets for this COMET Casestudy
are on line at:
http://www.joss.ucar.edu/cometCases/avail.html
for download via CODIAC or on 8mm tape.
