Regridding EURO CORDEX Data with generic grid

Added by Ivan Malik about 5 years ago

Hi,

I am totally new to cdo. I have a problem with my dataset. The grid is in a Euro Cordex Format: https://www.cordex.org/domains/cordex-region-euro-cordex/

I got this information:

cdo sinfo myfile.nc

File format : netCDF4
    -1 : Institut Source   Ttype    Levels Num    Points Num Dtype : Parameter ID
     1 : unknown  unknown  instant       1   1      7654   1  F32  : -1            
     2 : unknown  unknown  instant       1   1      7654   1  F32  : -2            
     3 : unknown  unknown  instant       1   1      7654   1  F32  : -3            
     4 : unknown  unknown  instant       1   1      7654   1  F32  : -4            
     5 : unknown  unknown  instant       1   1      7654   1  F32  : -5            
     6 : unknown  unknown  constant      1   1      7654   1  F32  : -6            
     7 : unknown  unknown  constant      1   1      7654   1  F32  : -7            
   Grid coordinates :
     1 : generic                  : points=7654 (89x86)
   Vertical coordinates :
     1 : surface                  : levels=1
   Time coordinate :  365 steps
  YYYY-MM-DD hh:mm:ss  YYYY-MM-DD hh:mm:ss  YYYY-MM-DD hh:mm:ss  YYYY-MM-DD hh:mm:ss

cdo griddes myfile.nc                                                                     
#
# gridID 1
#
gridtype  = generic
gridsize  = 7654
xsize     = 89
ysize     = 86
cdo griddes: Processed 7 variables ( 0.00s )

Its a regular lon/lat grid, but rotated and with a displaced pole, 0.5 degree resolution.

I found out that I have to use: cdo remapbil,targetgrid  -setgrid,sourcegrid  ifile  ofile

But I am not sure what I have to enter in the targetgrid and sourcegrid files. Can somebody please help me out?

hi!

targetgrid is the grid you want to interpolate your data to. the sourcegrid is the CORDEX grid, but it seems that the coordinates are not part of you data file. So CDO cannot figure out how to compute the interpolation weights.

Without the data it's really hard to help
