CDO

Hello,

I would like to have some help on the remapping/interpolation between SODA dataset and an ORCA025 grid.
I've tried the following codes:

1. Get only one variable as reference grid
   ncks -O -v umask,time_counter,nav_lon,nav_lat,nav_lev mesh_mask.nc mask_file.nc

1. Rename the variables
   ncrename -O -v nav_lon,lon -v nav_lat,lat -v time_counter,time -v nav_lev,depth mask_file.nc mask_file.nc

1. Perform the interpolation
   cdo remapbil,mask_file.nc soda_1981.nc output.nc

I keep receiving the same error (even when I don't change the variables' names):
Warning (find_time_vars): Time variable >t< not found!
cdo remapbil (Abort): Unsupported target grid type (generic)!

Here are the files I'm using as a test:
ncdump -h mask_file.nc
netcdf mask_file {
dimensions:
y = 1021 ;
x = 1442 ;
z = 75 ;
t = UNLIMITED ; // (1 currently)
variables:
float lat(y, x) ;
float depth(z) ;
float lon(y, x) ;
double time(t) ;
byte umask(t, z, y, x) ;

ncdump -h soda_1981.nc
netcdf soda_1981 {

The SODA file is too large to upload.
