[MITgcm-support] A question on external forcing timestep

[Christoph Voelker]

Hi Diego,

in data.exf you can specify a separate period for every forcing field.
I, for example use

 &EXF_NML_02
 uwindstartdate1   = 00010101,
 uwindstartdate2   = 120000,
 uwindperiod       = 86400.0,
#
 vwindstartdate1   = 00010101,
 vwindstartdate2   = 120000,
 vwindperiod       = 86400.0,
#
 ... more lines left away
 &

to prescribe daily (period = 86400 seconds) forcing, assuming that my
first record in the wind files starts on the first of january in year
0001, at 12:00 h. You should probably do something like

 uwindstartdate2 = 013000,
 uwindperiod = 10800.0,

Cheers, Christoph
