[ncl-talk] Incorrect plot

[Rashed Mahmood]

Hi Mauro,
I think the data file is poorly formatted. There are several issues with
the data, most important ones are:

*1) mismatch of dimensions between variable and the coordinates:*
Lat/Lon: Dimensions and sizes: [*yc | 912]* x [xc | 444]
prec:      Dimensions and sizes: [zt | 48] x [yt | 444] x [*xt | 912*]

This can be solved by dimension reordering (see in the attached script).

*2) The data contains NaNs:*
   GRISO hourly precip rate (mm/h) : min=-nan   max=-nan
 NCL has a special function to deal with these (see also in the attached
script).

Also you can use NCL's special attributes lat2d and lon2d for assigning 2d
coordinates to the variable (see in attached script).

The attached script seems to plot correctly, but make sure that dimension
reordering is correct (that is lat and lon are not swapped incorrectly).

Cheers,
Rashed
