Variable Type Description Default Value<br />

PMAP * char*8 Map projection<br />

UTM : Universal Transverse Mercator<br />

TTM : Tangential Transverse Mercator<br />

LCC : Lambert Conformal Conic<br />

PS : Polar Stereographic<br />

EM : Equatorial Mercator<br />

LAZA : Lambert Azimuthal Equal Area<br />

FEAST real False Easting (km) for PMAP= TTM, LCC, or LAZA 0.0<br />

FNORTH real False Easting (km) for PMAP= TTM, LCC, or LAZA 0.0<br />

IUTMZN integer UTM zone of coordinates for PMAP=UTM -<br />

UTMHEM char*4 Hemisphere (N or S) for PMAP = UTM N<br />

RLAT0 char*16 Latitude (decimal degrees N or S; e.g., 45.7N) of projection<br />

origin for PMAP= TTM, LCC, PS, EM, or LAZA<br />

RLON0 char*16 Longitude (decimal degrees E or W; e.g., 75.2E) of<br />

projection origin for PMAP= TTM, LCC, PS, EM, or LAZA<br />

XLAT1 char*16 Matching parallel #1 of latitude (decimal degrees N or S) for<br />

projection (Used only if PMAP= LCC or PS)<br />

XLAT2 char*16 Matching parallel #2 of latitude (decimal degrees N or S) for<br />

projection (Used only if PMAP= LCC)<br />

UTM<br />

DATUM char*8 Datum code for output coordinates WGS-84<br />

grid<br />

NZ integer Number of vertical layers -<br />

DGRIDKM real Grid spacing (km) of the meteorological grid -<br />

ZFACE real array Cell face heights (m) for the meteorological grid (NX + 1<br />

values must be entered). Note: Cell center (grid point)<br />

height of layer "i" is ((ZFACE(i+1) + (ZFACE(i))/2).<br />

XORIGKM real Reference X coordinate (km) of the southwest corner of grid<br />

cell (1,1) of the meteorological grid<br />
