Help with extracting rectangular selection based on longitude and latitude from netCDF
Added by Umed Maru 24 days ago
This issue has been making me tear my hair out for no reason (I have been trying to do this for 3+ hours with no avail).
I am a beginner with CDO and with working with netCDF files in general.
I am trying to extract a rectangle that is used for the Niño 3.4 index (-5 to 5 longitude, -170 to -120 latitude) from a netCDF file.
However the latitude and longitude are not dimensions, they are variables with makes it impossible to use the NCO ncks command.
I can't figure it out with CDO either, and I even tried using python but I am not savvy enough with this stuff.
PLEASE HELP!
I've attached two time slices from my file, if that helps.
