Hi Laurie, 

I suspect FSL (now GSD) maintains an archive as well as NCDC.

We maintain a short term archive to help for LDM outages, it appears that the 
profiler data only goes back a week.

The archive is at:

http://motherlode.ucar.edu/unidata/index.html

This site is passwd protected, so if you desire to access the data, let us know 
and we will send the passwd in another e-mail.
 

For THREDDS catalog (OPeNDAP server) please visit (same timeline):

http://motherlode.ucar.edu:8080/thredds/catalogServices?catalog=http://motherlode.ucar.edu:8080/thredds/idd/obsData.xml

GSD (FSL) informtion is at:

http://www.profiler.noaa.gov/npn/index.jsp

NCDC does not look promising:

Cheers, and glad to hear your connect to NSF is working!


Jeff
