Re: regridding problem

Hi Mike,

I think I see the issue:
sst = in->tas(0,0,:)

I believe what you want is:
sst = in->tas(0,:,:)

put a printVarSummary(sst) after each of those statements, and you will
see that the original line results in sst being a 1D array of size
sst&lon, while the replaced line will read in the first timestep's lat x
lon grid.

Good luck,
Adam
