cdo remapcon will not work with my file
Added by Jacob Spender over 5 years ago
I have been trying to conserve my Stage IV precipitation and tried to remap it to a 12,25 and 50km grid. I keep getting the error corners are missing. And have added a corner file, but it will still not work.
I attached the file for the grid box since the netcdf file for the Stage IV is 2.9 GB

hi!
Can you upload a single timestep? without the input grid it's really hard to be helpful.
cheers

Sorry about that here is the file.
also attached is a screen shot of the main data itself.

Your data has a curvilinear grid with only the cell center locations given. For conservative remapping, the cell areas have to computed, which needs the bounds of each cell. Because they are not present (and cannot be generally computed), remapcon cannot be run successfully
% cdo -P 8 info -remapcon,global_1 -selname,p01m StageIV_timestep.nc
cdo(2) remapcon: Process started
cdo(3) selname: Process started
-1 : Date Time Level Gridsize Miss : Minimum Mean Maximum : Parameter ID
cdo(2) remapcon (Abort): Source grid cell corner coordinates missing!
bilinear or nearest neighbor interpolation work fine

PS I do all my tests with the current release version 1.9.5
