Does CDSAPI have a zonal mean option?

Hi,

I have a retrieval script that looks like this

import cdsapi

C = cdsapi.Client()

YEARS = list(range(1992, 2025))
LEVELS = ['10', '20', '30', '50', '70', '100', '150', '200', '250', '300',
          '400', '500', '600', '700', '850', '925', '1000']

C.retrieve(
    'reanalysis-era5-pressure-levels-monthly-means',
    {
        'product_type': 'monthly_averaged_reanalysis_by_hour_of_day',
        'year': YEARS,
        'time': ['00:00', '06:00', '12:00', '18:00'],
        'download_format': 'zip',
        'variable': ['temperature', 'u_component_of_wind'],
        'pressure_level': LEVELS,
        'month': ['01', '02', '06', '07', '08', '12'],
    },
    'test.zip'
)

It works, but the download step struggles a bit with the size of the file. Ultimately I only need a zonal mean of these data. Is it possible to set that as an option in the API, similar to setting the grid size? Obviously this would make the file significantly smaller.

Thanks,

Ruth

Hi,
you can use the keyword ‘area’. Please use the webform to build your request: ERA5 monthly averaged data on pressure levels from 1940 to present

Thanks

Thanks @Michela, I’m not sure that does what I need. ‘area’ allows me to select a region of the globe. I want the whole globe, but averaged over longitudes.
