CDSAPI: reanalysis single-level is being download as a .zip when asked for "unarchived"

Hi there,

I’m trying to download data using python cdsapi using the following query:

{'product_type': ['reanalysis'], 'variable': ['top_net_thermal_radiation'], 'year': ['2024'], 'month': ['10'], 'day': ['31'], 'time': ['00:00', '01:00', '02:00', '03:00', '04:00', '05:00', '06:00', '07:00', '08:00', '09:00', '10:00', '11:00', '12:00', '13:00', '14:00', '15:00', '16:00', '17:00', '18:00', '19:00', '20:00', '21:00', '22:00', '23:00'], 'data_format': 'netcdf', **'download_format': 'unarchived'**}

While I explicitely require the unarchived netcdf data, the output is still downloaded as a zip archive. The archive contains two files that are:
data_stream-oper_stepType-accum.nc
data_stream-oper_stepType-instant.nc

I don’t understand what these “accum/instant” files are supposed to be

This is happening to me too.

This is an announcement regarding the changes. I hope this will be helpful to you.

Thank you.

In summary, the GRIB->netcdf converter now returns instantaneous and accumulated variables.

Hello,
So what changes should I make to my code to be able to get the data in netcdf format as in my code currently I use that NetCDF data from ERA5 to be converted to an excel sheet and I am getting unknown format error when my code try to process the .nc file downloaded from CDS
