Variable Type Description Default Value
ISTEPPG integer Timestep (hours) of the prognostic model input
data
IGFMET integer Use coarse CALMET fields as initial guess
fields
LVARY logical Control variable for use of varying radius of
influence. If no stations with valid data are
found within the specified radius of influence,
then the closest station with valid data will be
used. (T=use, F=do not use.)
RMAX1 real Maximum radius of influence over land in the
surface layer (km). This parameter should
reflect the limiting influence of terrain features
on the interpolation at this level.
RMAX2 real Maximum radius of influence over land in
layers aloft (km). RMAX2 is generally larger
than RMAX1 because the effects of terrain
decrease with height.
RMAX3 real Maximum radius of influence overwater (km).
RMAX3 is used for all layers overwater. It
must be large enough to ensure that all grid
points over water are large enough to be within
the radius of influence of at least one
observation.
RMIN real Minimum radius of influence used in the wind
field interpolation (km). This parameter
should be assigned a small value (e.g.,
