[GRASS-user] trouble with netCDF input arguments for r.in.gdal

[Kirk Wythers]

I am trying to read some netCDF data (from the CRU climate database) into grass. I am looking at the netcdf wiki page and having a little trouble translating the instructions there to the output I am getting from "gdalinfo". Here is the 

If I am trying to use syntax that looks something like:
r.in.gdal input=NETCDF:"sst.nc":time_bnds output=sst
I am getting the following error:

ERROR 4: `NETCDF:~/Downloads/cru_ts_3_10.1901.2009.pet.dat.nc:time_bnds' does not exist in the file system,
and is not recognised as a supported dataset name.

In my case, the PATH_TO_FILE is

"~/Downloads/cru_ts_3_10.1901.2009.pet.dat.nc"

However, I can't tell what to use in the place of ":time_bnds". Any ideas from the pasted text below of what my input argument should look like?

Thanks in advance,

Kirk


Here is output I am looking at from gdalinfo:
