maskregion problem
Added by Taixia Wu over 8 years ago
Hi, I used ncl_convert2nc to convert a OMI L3 data(.he5) to *.nc. CDO selname works good for the *.nc file, see the attached file. However, when I used cdo maskregion for this 200502sel.nc, it shows "*cdo maskregion (Abort): No regular grid found". The mask file have no problem. Should some problems of this 200502sel.nc data format? This problem confused me for a long time, is there anyone can help me. Thanks.

Hi!
The file does not contain any coordinated, only plain integers for gridsize (x,y). Hence, any kind of selection based on locations cannot work. You can use cdo to add location with w proper griddes
cdo -griddes -topo,r1440x720 > gd cdo setgrid,gd 200502sel.nc 200502sel_withGrid.nc
but you have to check the locations of cource!
