[ncl-talk] Smooth_color_map

[Adam Phillips]

Hi Kunal,
I see what you mean. The areas of missing data are not helping NCL come up
with a smoother field. Note: NCL will not alter the data istelf to obtain a
smoother look when plotting. That is left to the user. To smooth the data
manually you could try using smth9_Wrap:
http://www.ncl.ucar.edu/Document/Functions/Contributed/smth9_Wrap.shtml
Note that a grid point needs all the grid points neighboring it to be
non-missing to be smoothed. Beyond that function I am unsure what more to
suggest. Perhaps someone else can chime in with have another suggestion..
Adam
