How to regrid non latitude and longitude data?

Added by ep gupal almost 2 years ago

I was wondering if CDO supports non-latitude and non-longitude grid data.

Below is the information of the netcdf file that I am using.

The spatial grid is defined by x and y which are just zonal and meridional dimensions in meters.

@netcdf RCE_288x288x64.TB.p3.306k {
dimensions:
time = UNLIMITED ; // (1 currently)
x = 288 ;
y = 288 ;
variables:
float time(time) ;
time:standard_name = "time" ;
time:long_name = "time" ;
time:units = "day" ;
time:calendar = "proleptic_gregorian" ;
time:axis = "T" ;
float x(x) ;
x:units = "m" ;
x:axis = "X" ;
float y(y) ;
y:units = "m" ;
y:axis = "Y" ;
float PW ;
PW:long_name = "Precipitable Water" ;
PW:units = "mm" ;
PW:cell_methods = "time: mean" ;

// global attributes:
:CDI = "Climate Data Interface version 2.0.2 (https://mpimet.mpg.de/cdi)" ;
:CDO = "Climate Data Operators version 2.0.1 (https://mpimet.mpg.de/cdo)" ;
}@

What I would like to do is to regrid from 288x288 to 144x144.

Hi Ep,

I would say no, it is not possible to use CDO for your kind of files because the grid information is missing in both files.
