Matt,

- login as LDM  (~ldm is the LDM home dir, where ones ends up on login)
- add the path to the PATH environment var so the the deocders can be
found by the which command. Can be done in the .cshrc file, then do

% source .cshrc

Remember that all the cdl files and station files should be in the ldm/etc
directory.


Run this in the ldm home dir

% metar2nc etc/metar.cdl 0007 < "raw metar file"

could use  testdata.wmo for the raw file.

Robb...
