grib_to_netcdf examples
Produce a NetCDF file from grib edition 1
Code Block > grib_to_netcdf -o output.nc input.grib1
If your grib file has analysis and 6-hour forecast, then ignore keys 'type' and 'step'. Thus type=an/fc and step=00/06 will not be considered as netcdf dimensions.
Code Block > grib_to_netcdf -I type,step -o output.nc input.grib
Do not use time of validity. If time of validity is used, it means the 1D time coordinate is considered as date+time+step, otherwise 3 different dimensions are created.
The default behaviour is to use the time of validity.
Code Block > grib_to_netcdf -T -o output.nc input.grib
Produce NetCDF with data type of FLOAT (32bit floating point, for higher precision).
Note these types were chosen to provide a reasonably wide range of trade-offs between data precision and number of bits required for each value
Code Block > grib_to_netcdf -D NC_FLOAT -o output.nc input.grib
