Hi Muhtarjan ,

The array should be latxlon. If you don't do that I believe NCL will give you an
error message.. NCL also expects that you have the following attributes set:
(Assuming your data is stored in "array")
array&lat@units = "degrees_north"
array&lon@units = "degrees_east"
>And another thing, if latitude is N->S direction, should I change it to
>S->N before plotting?
NCL will handle both (N->S and S->N) when plotting. However, it is a good
practice to get into ordering your data array from S->N, as I believe the
spherical harmonic functions expect the data to run from S->N.
To flip the latitudes for array "finarr"(lat,lon):
newarr = finarr(::-1,:)
