Simple upscale method: which remapgrid?
Added by Matteo De Felice over 10 years ago
Hi,
I'm going to use cdo to perform an upscaling of a precipitation dataset on a coarser grid to match the grid of another field. I want to use probably the simplest method: if the destination grid is four times coarser I want to have each new point equal to the average of the four nearest points and so on... I checked the CDO documentation and the SCRIP one but it's not clear if this method is implemented. I don't have a climate science background and so I don't want to do something (very) stupid.
Thank you in advance for any help,
