sellonlatbox from rotated pole NetCDF

Added by Corso Quilici over 4 years ago

Hi,

I need to extract data from a location defined by coordinates.
I've tried to use sellonlatbox tool from the CDO library, but i get the following error:

cdo -sellonlatbox,10,14,40,44 lffd2006092610.nc new.nc

cdo sellonlatbox (Abort): Latitudinal dimension is too small!

I have also tried both remapnn and remapbil, on their own or in combo, but I always get an error:

cdo -remapnn,lon=10.0_lat=53.0 lffd2006092610.nc out.nc

cdo remapnn (Abort): Unsupported generic coordinates (Variable: vcoord)!

or

cdo -remapnn,lon=11.3_lat=42.5 -remapbil,r360x180 lffd2006092610.nc out.nc

cdo remapbil (Abort): Unsupported generic coordinates (Variable: vcoord)

Could someone please help me out?
I'm afraid the problem sits in the rotated pole projection, but I can't work my head around it.

Thanks!
Corso

Hi Corso,

can you upload the file (1 timestep)?

Hi Karin,
you can find the file here attached.
note that it's not the file i posted on the forum, but a different file.
the new file comes from the same simulation, and presents the same problem:

cdo -sellonlatbox,10.0,14.0,40.0,44.0 lffd2006092609.nc new.nc

gives me

cdo sellonlatbox (Abort): Latitudinal dimension is too small!

just like before.

thanks
Corso

The file contains some needless coordinate variables like vcoord. When selecting all variables the needless coordinates will disappear.

cdo -sellonlatbox,10.0,14.0,40.0,44.0 -selname,PMSL,TQV,TWATER,TWATFLXU,TWATFLXV lffd2006092609.nc new.nc
