Dear OCMIPeurs,

  The final PO4 monthly maps are available on ftp.
ftp to ftp.essc.psu.edu, cd to /pub/meteo/ferial, then mget *sur.ps + readme.
I only put some final surface maps in that directory. 

  The final file of PO4 data on regular 2 deg per 2 deg grid is also available 
on ftp (same directory).
the name of the file is 'po4map.dat.gz' and the fortran program to read it is
'readmap.f' in attachment of this mail. Please cp the data file as soon as 
possible so I can remove it from ftp , it takes too much space.

A bientot,
