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.

Then, you would have to bin the values.
Good Luck

Hi NCL-Talk,
I am attempting to compute bin the joint distribution of T-RH from climate model output.
ex.
T(lat,lon) = ((/10,15/),(/5,10/))
RH(lat, lon) = ((/60,50/),(/70,60/))
count = Bin(T= 10, RH = 60) = 2
count = Bin(T= 15, RH =50) = 1
count = Bin(T= 5, RH =70) = 1
Total count = 4
The issue that I am running into is that the grid cell sizes change as latitudes move away from the equator, emphasizing high latitudes vs low latitudes. I am not aware of an NCL function that accounts for the change in grid cell size while binning data. Is there one?
