compute div and vorticity

Added by Abdoulaye SARR over 12 years ago

I have a netcdf file with the following dimension and I want to compute div and vorticity but I am having a grid error ( not gaussian).
Any hint to solve it appreciate.

File format: netCDF
    -1 : Institut Source   Name        Time Typ  Grid Size Num  Levels Num
     1 : unknown  unknown  t           var  F32     20140   1       2   1
     2 : unknown  unknown  u           var  F32     20140   1       2   1
     3 : unknown  unknown  v           var  F32     20140   1       2   1
     4 : unknown  unknown  w           var  F32     20140   1       2   1
     5 : unknown  unknown  qvp         var  F32     20140   1       2   1
     6 : unknown  unknown  qcp         var  F32     20140   1       2   1
   Horizontal grids :
     1 : lonlat       > size      : dim = 20140  nlon = 190  nlat = 106
                        lon       : first = -38.8133  last = 29.17  inc = 0.3597  degrees_east
                        lat       : first = -11.61  last = 25.23  degrees_north

uv2dv works only if U and V are on a global regular Gaussian grid!
I will add this limitation to documentation in the next CDO release.
