[ncl-talk] Problem with CFS initial condition data plot in NCL

[Vimal Koul]

Hi Nicolas,

Thanks for your help.

But now, the following error messages are seen:

warning:ScalarFieldSetValues: 2d coordinate array sfXArray has an incorrect
dimension size: defaulting sfXArray
warning:ScalarFieldSetValues: 2d coordinate array sfYArray has an incorrect
dimension size: defaulting sfYArray
warning:ContourPlotDraw: out of range coordinates encountered; standard
AreaFill rendering method may be unreliable;
 consider setting the resource trGridType to "TriangularMesh" if
coordinates contain missing values
fatal:ContourPlotDraw: Workspace reallocation would exceed maximum size
100000000
fatal:ContourPlotDraw: draw error
fatal:ContourPlotDraw: draw error
fatal:PlotManagerDraw: error in plot draw
fatal:_NhlPlotManagerDraw: Draw error

Please note that I don't have the grid resolution information except nlat,
nlon and depth levels.

Modified script is attached.


Regards,
Vimal
