UTM
FEAST real False Easting (km) for PMAP= TTM, LCC, or LAZA 0.0
FNORTH real False Easting (km) for PMAP= TTM, LCC, or LAZA 0.0
IUTMZN integer UTM zone of coordinates for PMAP=UTM -
UTMHEM char*4 Hemisphere (N or S) for PMAP = UTM N
RLAT0 char*16 Latitude (decimal degrees N or S; e.g., 45.7N) of projection
origin for PMAP= TTM, LCC, PS, EM, or LAZA
RLON0 char*16 Longitude (decimal degrees E or W; e.g., 75.2E) of
projection origin for PMAP= TTM, LCC, PS, EM, or LAZA
XLAT1 char*16 Matching parallel #1 of latitude (decimal degrees N or S) for
projection (Used only if PMAP= LCC or PS)

DATUM char*8 Datum code for output coordinates WGS-84
NX integer Number of grid cells in the X direction of the meteorological
grid
NY integer Number of grid cells in the Y direction of the meteorological

NZ integer Number of vertical layers -
DGRIDKM real Grid spacing (km) of the meteorological grid -
ZFACE real array Cell face heights (m) for the meteorological grid (NX + 1
