Variable Type Description
FNORTH real False Northing (km) for PMAP = TTM,
LCC, or LAZA
IUTMZN integer UTM zone for PMAP = UTM
UTMHEM character*1 Use (N) northern or (S) southern
hemisphere for UTM projection
RLAT0, RLON0 character*16 Reference latitude and longitude (degrees)
for PMAP = TTM, LCC, PS, EM, or
LAZA. Enter numeric degrees and either N
or S for latitude, or E or W for longitude.
RLAT1, RLAT2 character*16 Two standard parallels of latitude for
PMAP= LCC or PS. Enter numeric degrees
and either N or S.
DATUM character*8 Datum Code for output grid
IGRID Integer Grid definitions are: (1) Cartesian-corner,
(2) Cartesian-Center, (3) Polar. For
CALMET, IGRID should be set to (1).
XREFKM,
YREFKM
Real
Reference X and Y coordinates origin (km)
of the output grid.
NX, NY integer Number of grid cells in X and Y directions
(if IGRID=1 or 2).
DGRIDKM Real Horizontal grid spacing (km).
NRING,
NRAYS
integer
Number of rings and radials (if IGRID=3).
IPROC integer Terrain extraction approach for polar grid
only:
(1) NORMAL=Terrain data extracted from
the region extending halfway to previous
ring and halfway to next ring.
(2) SCREEN=Terrain data extracted from
the region extending from the current ring
out to the next ring distance.
