[MITgcm-support] EXF and time-interpolation again

[Lars Czeschel]

Hi MITgcm users,

is there any difference in the  time-interpolation of the forcing
with or without the EXF package.

I usually using climatological monthly mean forcing as in the
tutorial_global_oce_latlon or global_with_exf example.

I noticed that the monthly mean ustress/vstress output from
tutorial_global_oce_latlon and global_with_exf
is different (they both use the same windstress forcing).

The forcing output fits better after changing the startdate in
data.exf to the middle of the month, e.g.:
ustressstartdate1=19910116,
repeatPeriod = 31104000,
although it is not identical to tutorial_global_oce_latlon.
(with/without spatially interpolation in data.exf).

Thanks for any comments,
Lars
