[MITgcm-support] important changes to package "exf"

[Patrick Heimbach]

Hi there,

we've made a few changes to the external forcing package "exf"
which affects the way you specify runtime parameters in
data.exf, data.exf_clim, data.pkg

Those changes came into effect yesterday,
and are as of checkpoint59.
They should not affect results, it's just restructuring.

A brief summary:

o data.pkg:
-----------
You now need to set runtime parameter
   useEXF = .TRUE.,
if you want to use exf

o data.exf_clim:
----------------
This file has been retired, corresponding parameters are
now set in data.exf

o data.exf:
-----------
We have split up the original namelist EXF_NML
into four namelists EXF_NML_01, ..., EXF_NML_04
Examples on how to use these are given in
verification/global_with_exf/input/data.exf
verification/lab_sea/input/data.exf

The details of what goes into which namelist can be inferred
from routine exf_readparms.F

Sorry for the inconvenience
(but will be beneficial in the long term).

-Patrick
