The CDSAPI allows users to conveniently download the data they require via python.

Users can also specify the Area of interest that they would like to retrieve using the Area keyword.

import cdsapi

dataset = "derived-utci-historical"
request = {
    "variable": ["universal_thermal_climate_index"],
    "version": "1_1",
    "product_type": "consolidated_dataset",
    "year": ["2020"],
    "month": ["09"],
    "day": ["29"],
    "area": [45, -120, -45, 120]
}

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