cdo remapbil (Abort): Unsupported grid type: generic

Added by Jing Sun almost 8 years ago

I want to remap my data to r360*360, "cdo -remapbil,r360*360 HadISST_sst.nc HadISST_sst.5degree.nc"
but it shows :cdo remapbil (Abort): Unsupported grid type: generic
I have tried https://code.zmaw.de/boards/1/topics/513, but it doesn't work.
Here are the head information of my data,
etcdf HadISST_sst {
dimensions:
time = UNLIMITED ; // (1763 currently)
latitude = 180 ;
longitude = 360 ;
nv = 2 ;
variables:
float time(time) ;
time:units = "days since 1870-1-1 0:0:0" ;
time:calendar = "gregorian" ;
time:long_name = "Time" ;
time:standard_name = "time" ;
float time_bnds(time, nv) ;
float latitude(latitude) ;
latitude:units = "degrees_north" ;
latitude:long_name = "Latitude" ;
latitude:standard_name = "latitude" ;
float longitude(longitude) ;
longitude:units = "degrees_east" ;
longitude:long_name = "Longitude" ;
longitude:standard_name = "longitude" ;
float sst(time, latitude, longitude) ;
sst:_FillValue = -1.e+30f ;
sst:standard_name = "sea_surface_temperature" ;
sst:long_name = "sst" ;
sst:units = "C" ;
sst:cell_methods = "time: lat: lon: mean" ;
sst:missing_value = -1.e+30f ;

// global attributes:
:Title = "Monthly version of HadISST sea surface temperature component" ;
:description = "HadISST 1.1 monthly average sea surface temperature" ;
:institution = "Met Office Hadley Centre" ;
:source = "HadISST" ;

}

since it is too big , i will just attached 10 years version.
Thanks a lot for helping.
Best,
Amber

Here is the result of "cdo sinfon HadISST_sst.test.nc" (with cdo version 1.7.1):

CDO found 2 data variables, the first variable time_bnds has 2 points and no grid information. Such a variable can't be interpolated with CDO. In this case you need to select the variable sst for the interpolation:
cdo remapbil,r360*360 -selname,sst HadISST_sst.test.nc result
