[ncl-talk] Missing values are regridded?

[Karin Meier-Fleischer]

Hi Lifen,

you should try to rearrange the following lines like

load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl"  
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/shea_util.ncl" 
load "$NCARG_ROOT/lib/ncarg/nclscripts/esmf/ESMF_regridding.ncl"

Bye,
Karin
