[ncl-talk] regridding routine for grids with 2D lat and lon

[Diana Stovern - NOAA Affiliate]

Hello,

I need to regrid rainfall data from a lambert conformal grid to a polar
sterographic grid.  The lat and lon data in both grids are 2D arrays (see
filedump output below).  Is there a regridding routine in NCL that allows
for both the input and output lat and lon to be 2D arrays?  I see most of
the routines require lat and lon to be 1D arrays.

Thanks!
