I try to download “reanalysis-era5-single-levels” from ERA5 hourly data on single levels from 1940 to present.
but they return “Not Found” Error in client download parts in python.
Here are my codes and error return.
codes are automatically genereted in the below site.
https://cds.climate.copernicus.eu/datasets/reanalysis-era5-single-levels?tab=download
moreover, I try to set url of “.cdsapirc” file as both ewds, cds like below.
