Variable Type Description
ITERREP integer Application of default elevations by
water/land type (5 values)
0 = Do not replace voids
1 = Replace voids on output only
2 = Replace void point values on extraction
and voids on output
3 = Always replace all values for this water
type with default (only valid for oceans and
lakes)
TERDEF integer Default elevation (m) for cells or discrete
points that cannot be assigned valid data (5
values)
LVOIDFIL logical Carry out interpolation to fill void cells
(T=yes, F=no)
CELLRADKM real Search radius (km) around grid cells for
interpolation to fill voids (Should be
several times larger than DGRIDKM)
(Used only if LVOIDFIL=T)
IMODEL integer (1,..,6)
Meteorological or dispersion model using
terrain data; options are: (1) CALMET, (2)
MESOPAC, (3) ISC3 polar grid receptor
terrain format, (4) ISC3 discrete receptor
format; (5) NUATMOS, or (6) GENERIC.
ITHRES integer Threshold flag in % of the average number
of data 'hits' per cell used for QA reporting.
MSHEET integer Choice of mapping terrain elevations.
Transform 4 corners of data sheet and
interpolate, or, transform each data point in
the sheet from lat, lon to x,y. Preferred
method MSHEET = 1. Data sets affected;
USGS90, ARM3, 3CD, CDED, SRTM1,
SRTM3, GTOPO30.
