remapnn working
Added by matteo borgnino over 2 years ago
Hi,
I using remapnn,lon,lat to extract lon lat data from my netcdf files.
I would like to know more about remapnn but I could not find information about how it works.
I know it performs a nearest neighbor remapping, but how? which kind of interpolation?
thanks a lot

hi Mateo!
you can check the official documentation https://code.mpimet.mpg.de/projects/cdo/embedded/cdo.pdf, page 164
basically you look for the gridpoint with the smallest great circle distance on the sphere
cheers
