Currently only string should be used in an API request.

Analysis data are not available on the ADS webform but they can be downloaded using the CDS API service. The keyword 'type' and 'leadtime_hour' have to be set on 'analysis' and '0' respectively. Please have a look at the following example:

import cdsapi

c = cdsapi.Client()

c.retrieve(
    'cams-global-atmospheric-composition-forecasts',
    {
        'date': '2021-03-24',
        'time': [
            '06:00', '12:00', '18:00',
        ],
        'leadtime_hour': '0',
        'area': [
            70, -18, 69,
            -17,
        ],
        'type':'analysis',
        'variable': 'total_aerosol_optical_depth_670nm',
        'format': 'netcdf_zip',
    },
    'download.netcdf_zip')

A subset of the CAMS Global atmospheric composition forecast data for the latest three days can be accessible also through the FTP dissemination service. For list of variables available on the FTP please see here.
