<strong>CALPUFF</strong> Control File Inputs - Input Group 4<br />

Grid Control Parameters<br />

Variable Type Description Default Value<br />

IBCOMP integer X index of lower left corner of the computational grid<br />

(1 # IBCOMP # NX)<br />

JBCOMP integer Y index of lower left corner of the computational grid<br />

(1 # JBCOMP # NY)<br />

IECOMP integer X index of upper right corner of the computational grid<br />

(IBCOMP # IECOMP # NX)<br />

JECOMP integer Y index of upper right corner of computational grid<br />

(JBCOMP # JECOMP # NY)<br />

LSAMP integer Flag indicating if an array of gridded receptors (i.e.,<br />

sampling grid) is used<br />

(T = yes, F = no)<br />

IBSAMP integer X index of lower left corner of the sampling grid (IBCOMP<br />

# IBSAMP # IECOMP)<br />

JBSAMP integer Y index of lower left corner of the sampling grid (JBCOMP<br />

# JBSAMP # JECOMP)<br />

IESAMP integer X index of upper right corner of the sampling grid<br />

(IBCOMP # IESAMP # IECOMP)<br />

JESAMP integer Y index of upper right corner of the sampling gird<br />

(JBCOMP # JESAMP # JECOMP)<br />

MESHDN integer Nesting factor of the sampling grid<br />

(MESHDN $ 1). The grid spacing of the sampling grid is<br />

DGRIDKM/MESHDN. The number of sampling grid points<br />

is NXSAM * NYSAM, where<br />

NXSAM = MESHDN * (IESAMP - IBSAMP) + 1<br />

NYSAM = MESHDN * (JESAMP - JBSAMP) + 1<br />
