Section 2: Geophysical Data Processors Table 2-3 (concluded) TERREL Control File Inputs Input Group 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. 2-25
