Description :
- fields are analyses for 0000 UTC, 0600 UTC, 1200 UTC and 1800 UTC
or monthly means of daily means for time 0000 UTC;
- data are stored in FM 92 GRIB using sufficient bits to ensure that
the values represented can be retrieved to an accuracy consistent with
the analysis method used;
- Internal data is represented on a N80
Gaussian grid (80 lines of latitude, located according to a Gaussian
distribution between the pole and the equator for each hemisphere);
