when i use the command cdo -b 32 sp2gpl vort.spec.2012.nc vort.spec.2012.sp2gpl.nc, I get a Gaussian grid with 128x64 points. I want to get a T62 Gaussian grid with 192x94 points. I know i can set the value of trunc, which can be calculated by the formula of trunc = (nlat 2 − 1)/ 3. nlat is the number of latitudes of the resulting Gaussian grid. But the command cdo -b 32 sp2gpl,64 vort.spec.2012.nc vort.spec.2012.sp2gpl.nc is unuseful, what can i do for getting a T62 Gaussian grid with 192x94 points through the command sp2gpl?
Try it with sp2gp:
cdo -b 32 sp2gp vort.spec.2012.nc vort.spec.2012.sp2gp.nc
