ERA5Land return zip even with "unarchived" option

Hi,

I’m making requests to get some data over Ivory Coast but for 01/01/2026 it returns a zipped file with a separate netcdf for volumetric_soil_water_layer_1.

With the option unarchived it should return only a singe netcdf file (this is the case for all other days of the year).

import cdsapi

dataset = “reanalysis-era5-land”
request = {
“variable”: [
“2m_dewpoint_temperature”,
“2m_temperature”,
“volumetric_soil_water_layer_1”,
“10m_u_component_of_wind”,
“10m_v_component_of_wind”,
“surface_pressure”,
“total_precipitation”
],
“year”: “2026”,
“month”: “01”,
“day”: [“01”],
“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”,
“area”: [11, -9, 3, -2]
}

client = cdsapi.Client()
client.retrieve(dataset, request).download()
