[ncl-talk] Retrieving number of observations used in regridding

[Archana Dayalu]

Hi,
I am using NCL to regrid various datasets (MODIS Sinusoidal grid source,
500m, to a rectangular grid destination, coarser resolution, e.g., 3km),
and was wondering if there is a way to retrieve the number of non-missing
observations used in the regridding. For instance: if a gridcell in my
final regridded dataset involved a bilinear interpolation of n gridcells in
the grid source file, only m of which contained non-missing observations,
is there a way to retrieve the m quantity? Is this saved in any of the
regridding weights files? (I'm trying to retrieve that quantity so that the
uncertainty bounds of the values in my final regridded product could be
linked to the number of actual observations used in the calculation of each
regridded value).
Thanks very much for any help.
Regards
Archana
