Re: Query about uv2dvG_Wrap and gradsg

Soumik

The following NCL help page describes the difference between various
commonly-used grid types:

http://www.ncl.ucar.edu/Document/Functions/sphpk_grids.shtml#GaussianGrids

If I recall correctly, CAM3.0 output is on a fixed rather than a Gaussian
grid (in particular the latitude are equally evenly spaced throughout the
domain).

Try using uv2dvF_Wrap() and gradsf() functions.
