Re: Map distorted

Hi Ahmed,

After experimenting with your script a bit, it looks like two things are going on:

i) If you want to use the resource

  "res@tfDoNDCOverlay = True",

then you definitely need to set

  res@mpCenterLonF = 180

or else the data are out of phase 180-degrees with the basemap.

ii) It looks like ncview is using many more contour levels than the default in NCL; I got something much more interesting by setting:

    res@cnLevelSelectionMode = "EqualSpacedLevels"
    res@cnMaxLevelCount = 50
    res@cnLinesOn = False

I also experimented with different colormaps.

I hope that helps…
Rick

>> I am trying to plot correlation map from netcdf file(I have attached it), but the output is very distorted. I have attached the script also. I think that there is no missing value or Fill value in the file. I plot the file with ncview and it is different from what I got from the NCL. Any suggestions.
