Dale,

The dcuair decoder actions provided in
$NAWIPS/ldm/etc/templates/pqact.gempak_decoders.in
have a pattern for operational dropsonde data in the real-time IDD data
stream.
Once decoded into GEMPAK upper air files, NSHARP can be used to display
the dropsondes by clicking on the "DROP" file type under the Observed
Soundings.
You can also use any of the available "SN" programs to analyze that
data.

If you have other data not in the broadcast format that you want to get
into GEMPAK format, the easiest way to to create an ASCII input file in
the format that SFLIST outputs such as:

Once data is in this type of format, use the SNEDIT program to read the

If you can describe your data, or expected format, I can help in
how to format your data for use with GEMPAK.

Hello All,

I'm trying to get started with GEMPAK and could really use some help. I have GEMPAK downloaded and unzipped on my Sun machine, but I'm not sure how to proceed from there. I am doing research on Hurricanes and need to produce soundings from dropsonde data. I'm hoping to use the program NSHARP to do this. So once I can get NSHARP running I could use some assistance with formating the dropsonde data so it can be read into NSHARP. Any help is greatly appreciated. Thanks for your time!
