Dear ECMWF team, can you all please confirm whether this is anticipated behavior or a bug in back-end processing? If the latter my team will need to modify some of our ETL scripts ASAP to avoid major issues with data transformation.

Somtehing I found out is that queries sent via API now need to have two new parameters in order to get a netcdf file. If not used together you will get a zip file with either a netcdf or a grib file depending on the combination of new and old parameters.

Those parameters are:
‘data_format’: ‘netcdf’,
‘download_format’: ‘unarchived’,

Let me know if that works
