Erik,
You could resample or you could interpolate
Resampling (skipping certain grids) use the var(::2,::2) convention
for instance to resample the 0.5 x 0.5 gridded variable (var1) every other grid points, do:
[assume var1 has 4 dimensions, time, level, lat, lon and you want to
resample along lat and lon dimensions ]
newvar=var1(time|:,level|:, lat|::2,lon|::2)
Regrid - check up the regridding functions in NCL (see the applications page,
rightmost column)
hope it helps,
saji
