[gdal-dev] Problem opening new format ECMWF grib files

[Simon Proud - STFC UKRI]

Hello,
I'm trying to open a grib format file from ECMWF. The file is generated using the ECMWF open data python library as follows:

from ecmwf.opendata import Client
client = Client()

result = client.retrieve(
    type="fc",
    param="skt",
    step="0",
    target="data.grb2",
)

This produces a grib file I can read with cfgrib and eccodes but not with gdal:
>>>gdalinfo data.grib2
      getdrstemplate: DRS Template 5.42 not defined.
      ERROR 4: data.grib2 is a grib file, but no raster dataset was successfully identified.
             gdalinfo failed - unable to open 'data.grib2'.


I suspect this may be due to changes in their grib format, see: https://confluence.ecmwf.int/display/COPSRV/Implementation+of+IFS+cycle+48r1+for+CAMS#ImplementationofIFScycle48r1forCAMS-DefaultpackingtypesfordatafromDisseminationandMARS


Am I correct in this assumption and, if so, is there a way around it in GDAL? Otherwise, any clues what could be the problem with this grib?

Thanks,
Simon
