CDO

I would like to use cdo remapmedian,grid to decimate a very fine resolution grid to a coarser one. The fine resolution grid is for land only, with missing values over the oceans. When I process the data, it seems that any coarser resolution grid that has a single missing value in the fine resolution grid in it is set to missing.

The way I think I understand cdo remapstat should work, is that when estimating area statistics a missing value should just not count, but the statistical value should be calculated on the remaining valid cells. Am I incorrect? Do I need to set a flag somehow to get CDO to ignore the missing values as long as there is at least one non-missing value in the source grid?

Using CDO v2.1.0.

Thanks,
