[ncl-talk] Subscript out of range on call to grad_latlon_cfd from V6.4.0

[Rick Brownrigg]

Hi Ryan,

The way I read the docs for grad_latlon_cfd is that the 2nd and 3rd
arguments are coordinate *arrays* with lat/lon values, not scalars that
represent the dimensions of tc_rect_plane.  I'm not sure what those arrays
should be in your case, but perhaps this gets you further along (?)

HTH...
