Hi there, I was wondering if it would be possible to get the sum instead of the mean or (any other regridding method). In our data, in many cases we need to aggregate mass to coarser resolution. In theory, we can just multiply the output of average method with number of pixels. But, due to differing size of valid pixels (non nodata values) in each window, it won't produce an accurate result. I would be grateful if anyone can point me to 1) an alternate way to get the number of valid pixels in each regridding window) or 2) get the sum within the regridding window or 3) the location in the source where average method of resampling is implemented so that I can edit the source and build from scratch. Thank you.
