function canopy_calcdx

Calculate grid cell distances for 1D arrays.

subroutine canopy_dxcalc_mod::canopy_calcdx (
    DXOPT DXOPT,
    DXSET DXSET,
    NLAT NLAT,

Parameters:

DXOPT User DX calculation option (0=calculate, 1=use set value)
DXSET User DX set value if cannot calculate (m)
NLAT Number of latitude grid cells/points
NLON Number of longitude grid cells/points
LAT Model latitudes array (degrees)
LON Model longitudes array (degrees)
DX Distance between two points (m)
