Improvements for the surface forcing codes
current suggestions
- Include some revised standard method for converting FNMOC data.
This should include automated searching for a file based on the desired time
and the designations.

- Will need similar for Unidata.
- The current scheme is to combine the above fields according to standard
formula (including one for incoming solar radiation) to produce net heat flux,
E-P, wind stress and shortwave radiation. A more sensible approach might be
to grid the above fields and combine them in the PE model. The immediate
advantages I see are:
- Diurnal solar radiation is better modeled, without expanded data files.
- Using the supplied duration of each fields allows relaxing each input
to climatology at its own rate.
- Model SST can be used for greater consistency. This also gets around
the short (2.5 day) limit.
