processing the new grib2 compression format for ECMWF forecast data

[taupirho]

I wondered if anyone has tested out using xarray and the cfgrib engine to read the proposed new GRIB CCSDS compression format. We use xarray all over the place to read GRIB files but when I tried it on the new file format I received the following error.

FunctionalityNotEnabledError: Functionality not enabled

The file I downloaded to test can be found here: https://xdiss.ecmwf.int/ecpds/home/opendata/20230517/00z/0p4-beta/enfo/20230517000000-0h-enfo-ef.grib2

The code I used was: (xarray version is 0.20.1, and for cfgrib the version is 0.9.10.3)

import xarray as xr
import cfgrib
ds = xr.open_dataset('C:\Users\I35027\Downloads\20230517000000-0h-enfo-ef.grib2',
engine='cfgrib',filter_by_keys={'shortName': '2t','dataType':'pf', 'typeOfLevel':'heightAboveGround'}
)

FYI,

python -m cfgrib selfcheck
Found: ecCodes v2.23.0.
Your system is ready.

This is for ECMWF open data weather forecast 15-day datasets, URL is : https://www.ecmwf.int/en/forecasts/datasets/open-data

I found the answer. needed to upgrade my eccodes library to the latest version 2.30.0
