Surface meteorological forcing data

The forcing time step is controlled with the configurable resource variable __FORCE_DTSTEP__ and __must match the frequency of the input forcing files__.
Specify FORCE_DTSTEP=3600 [seconds] for GEOS products, incl. MERRA, MERRA-2, FP, and FP-IT/RP-IT, which are 1-hourly datasets.

The spatial (horizontal) interpolation method for the met forcing is controlled
by `MET_HINTERP` (see optional parameters in `exeinp` input file to ldas_setup).
