[MITgcm-support] external forcing input interpolation

[Nicolas Wienders]

Dear all, here are two small questions (for Patrick?):

When using the interpolation of input fields, one
has to provide the following attributes in the data.exf file:

field_lon0
field_lon_inc
field_lat0
field_lat_inc
field_nlon
field_nlat


1- How is the interpolation in longitude done since there
      is no specification of the longitude range of the model
      grid in the "data" file (like there is in latitude by specifying
     phiMin)?


1.5- If i am correct and by checking the code, field_lon_inc
     and field_lat_inc can be negative, right?

2- I don't understand in the manual (page 299) and in the
     global_with_exf exemple, the value for hflux_lat_inc=39*4.

    Shouldn't that be just: hflux_lat_inc=4    ?

    Or if not, shouldn't we have hflux_lon_inc=89*4   ?



Thanks a lot. have a good day. nw
