[ncl-talk] cmorph rainfall

[Adam Phillips]

Hi Geeta,
The error message is telling you that there might be something amiss with
the coordinate variables of your array that will be plotted.

Looking at your script you have this:
nlat        =  1649
lat         = -59.963614 - ispan(0,nlat-1,1)*0.072771377

you then assign the lat array as a coordinate variable to the array to be
plotted. Running those two lines of code you end up with latitudes that run
from -59.96 through -179.8908. I am guessing that that is causing your
issue. You might want to check your lon array as well as those only run
from 0-352.

Hope that helps. If not, please respond to the ncl-talk email list.
Adam
