Hi Bill,

There is a section of the GEMPAK workshop tutorial that covers importing 
surface data into GEMPAK sf file format, this is probably the document you 
mentioned. It requires a station table be created if the data are not tied to 
existing surface stations.

http://www.unidata.ucar.edu/software/gempak/tutorial/importing_data.html

There is no easy way to convert a CSV file to a GEMPAK surface station file, 
you will need to create a script to re-format your file.  I've done something 
similar with importing the NCAR surface station table to GEMPAK format in 
Python:

If you go this way, you'll have to use rjust() on your strings to get the 
formatting correct:
