Problems with remapcon. Newbie here.
Added by Giacomo Lucidi over 4 years ago
Hello everyone.
I'm new with CDO.
My task is to regrid a file (curvilinear grid) to the grid of another file (horizontal).
I'm having some problems with file (curvilinear grid) and not only with remapcon command but they might be connected.
1)cdo -info filecurvilinear.nc
Warning (cdf_set_var): Inconsistent variable definition for XLAT!
Warning (cdf_set_var): Inconsistent variable definition for XLONG!
Warning (cdfScanVarAttr): NetCDF: Variable not found - >XTIME<
(the command give me the information anyway but I don't understand the Warning advices.)
2)cdo -griddes filecurvilinear.nc
(same warnings)3)cdo -remapcon,weightfile.txt filecurvilinear.nc output.nc
(same warnings)
cdo remapcon (Abort): Source grid cell corner coordinates missing!I really don't know how to proceed.
I attached here both file with hourly...(curvilinear grid) and MERRA... (horizontal grid).
Thank you!!

Hi Giacomo,
there is an easy way to repair it:
cdo copy hourly_d02_2008-12-01_23_00_00.nc tmp.nc
Then remap to the MERRA grid:
cdo remapbil,MERRA_IVT_20060106_00.nc tmp.nc outfile.nc

Thank you Karin.
Can I ask you why remapcon doesn't work? Is it wrong the concept to regrid from curvilinear to horizontal with remapcon?
Thank you.

You can not use remapcon because the source grid cell corner coordinates are missing in your file.

Got it.
And could you explain me the command copy. I read on the guide but I can't understand the utility and why is necessary in my case.
Thank you for your help.
