[ncl-talk] Complicated Task

[Dennis Shea]

Re: "I am not aware of an NCL function that accounts for the change in grid
cell size while binning data.  Is there one?"

Answer: No.

I think you are looking for a, say, 25km x 25km global grid.

I suggest looking at the EASE grids: Maybe you can find a data set that
contains predefined lat/lon grids.

http://nsidc.org/data/ease

Then, you would have to bin the values.

Good Luck
