The AAPP update release V3.1 consists just of this readme file
containing an email from CMS/Meteo-France offering access to
up-to-date calibration and clock error files on their ftp server.


Dear AAPP users,

Because at CMS sometimes, we have to modify the files of coefficients
necessary to calibrate the different instruments of the NOAA satellites,
we feel that it could help some of you to have access to our operational
files.
For example, we can modify the limit values of output counts when the
radiometer is looking to the Space or the internal target. 

Normally, via the AAPP forum, you are informed about an upgrade of those
files. 

So the files will be put each day (0h15 UT) on a ftp server. 
Please remember that these files can contain errors as they are sometimes
manually updated, so you should not use them as truth. 
Some comments could be in French because inserted by our operators. 
The copy on the server is done by cron on a development machine, it can
be stopped at any time. Knowing this inconvenience we still think that
it can help.

Server: ftp.meteo.fr  (user: anonymous, pswd=your email address)
Directory: /pub/CMS/deliverables/aapp/calibration/coef/
One sub-directory for each instrument (we keep the AAPP scheme): 
  amsua  amsub avhcl hirs msu
Files for amsua: amsua_clcoefs.dat
                 amsua_clparams.dat
Files for amsub: amsub_bias.dat
                 amsub_clcoefs.dat
                 amsub_clparams.dat
(Note that updates of amsua and amsub files come from UKMO)
Files for avhrr: avhcal.txt
Files for hirs : calcoef.dat
Files for msu  : calcoef.dat

Additionally, we also update on our ftp server clock error information
for the different NOAA satellites in
Directory: /pub/CMS/deliverables/aapp/navigation/orb_elem/
