The cfgrib project offers to open a GRIB file as an xarray.Dataset: ```

import cfgrib cfgrib.open_dataset('era5-levels-members.grib') <xarray.Dataset> Dimensions: (air_pressure: 2, latitude: 61, longitude: 120, number: 10, time: 4) Coordinates: * number (number) int64 0 1 2 3 4 5 6 7 8 9 * time (time) datetime64[ns] 2017-01-01 ... 2017-01-02T12:00:00 step timedelta64[ns] ... * air_pressure (air_pressure) float64 850.0 500.0 * latitude (latitude) float64 90.0 87.0 84.0 81.0 ... -84.0 -87.0 -90.0 * longitude (longitude) float64 0.0 3.0 6.0 9.0 ... 351.0 354.0 357.0 valid_time (time) datetime64[ns] ... Data variables: z (number, time, air_pressure, latitude, longitude) float32 ... t (number, time, air_pressure, latitude, longitude) float32 ... Attributes: GRIB_edition: 1 GRIB_centre: ecmf GRIB_centreDescription: European Centre for Medium-Range Weather Forecasts GRIB_subCentre: 0 history: GRIB to CDM+CF via cfgrib-0.9.../ecCodes-2... It would be very helpful to have a backend for it distributed with *xarray* to be selected via the `engine` keyword argument: import xarray as xr xr.open_dataset('era5-levels-members.grib', engine='cfgrib') <xarray.Dataset> Dimensions: (air_pressure: 2, latitude: 61, longitude: 120, number: 10, time: 4) Coordinates: * number (number) int64 0 1 2 3 4 5 6 7 8 9 * time (time) datetime64[ns] 2017-01-01 ... 2017-01-02T12:00:00 step timedelta64[ns] ... * air_pressure (air_pressure) float64 850.0 500.0 * latitude (latitude) float64 90.0 87.0 84.0 81.0 ... -84.0 -87.0 -90.0 * longitude (longitude) float64 0.0 3.0 6.0 9.0 ... 351.0 354.0 357.0 valid_time (time) datetime64[ns] ... Data variables: z (number, time, air_pressure, latitude, longitude) float32 ... t (number, time, air_pressure, latitude, longitude) float32 ...
