gribtocdl level table
The table below explains the different GRIB levels (#) recognized by gribtocdl and their corresponding suffix in netCDF format. The suffix is used with the parameter name to specify what type of levels each parameter is given for. Units used in netCDF format is also given where applicable.| # | Suffix | Units | Description |
