CDO Error (cdf_get_att_double)
Added by Joseph Kuchar over 9 years ago
Hi,
I just installed cdo so that I can regrid a netcdf file with Greenland topography information. However, when I just use the command cdo info Greenland2km.nc, I get the error "Error (cdf_get_att_double) : NetCDF: Attempt to convert between text & numbers."
The full output is as follows:
cdf_get_att_double : ncid = 65536 varid = 1 att = latitude_of_projection_origin val = 1.15547907e-312
Error (cdf_get_att_double) : NetCDF: Attempt to convert between text & numbers
The netcdf file I'm trying to work with can be found here: http://websrv.cs.umt.edu/isis/index.php/1km_Greenland_data_set
I appreciate any help!
Thanks,
Joseph Kuchar

Hi,
I think the problem is, your file contains a character variable called "mapping" (see ncdump -h), which doesn't have any co-ordinates but is used by other variables. I guess it provides the information regarding mapping/projection. You could try using the NCO operator ncks for extracting a particular variable and then use CDO afterwards. For example,
ncks -h -v topg Greenland2km.nc green_topo.nc
extract the "Bedrock Topography" variable. Now "cdo sinfo green_topo.nc" should work but you may have to use the "mapping" information when you regrid/remap.
Cheers,
