[ncl-talk] gsn_csm_contour_map plot

[Wensong Weng]

Dear NCL Group,



I am using the gsn_csm_contour_map function to make a contour plot for the precipitation, see the attached. However, there are lots of un-wanted ‘noises’ outside of CONUS (no data).  The data is a one dimension array with unstructured grids. How can I get rid of those ‘noises’ and only draw the contour map over the CONUS.



Your help is greatly appreciated,
