How to regrid population data (total not density)

Added by Alexander Killick over 3 years ago

I have a population grid of 1/8th * 1/8th degree which displays total population per grid square,

I want to change this to a 1.875 * 1.25 degree population grid with total population per grid square.

Important to note this is total population per grid square not population density there it is not a flux so cannot be regridded simply by conservative remapping

Hi Alexander,

In CDO, the operator remapsum has been available since version 1.9.10. This operator has the status experimental. There is no documentation yet and the name may change in future versions. Currently, only regular lonlat grids are supported as targets. However, I think this operator already works very reliably and can therefore already be used. Besides sum there are also all the other CDO statistic functions like min, max, range, mean, median, std, var and so on.

cdo remapsum,<targetgrid>  infile outfile

You feedback is very welcome.

Cheers,
Uwe
