Hyperparameters used to generate the global dataset of urban areas and their rural surroundings. Some hyperparameters are common across cities and spatial resolutions, while others are defined ad hoc for each city and are included in the accompanying YAML file available in the GitHub repository referenced in the “Code Availability” section.

Hyperparameter	CORDEX-CORE	CORDEX-EUR-11
lon_city and lat_city	See YAML file
lon_lim and lat_lim	Typically, “lon_lim” = 1 and “lat_lim” = 1, but some cities require higher limits
urban_th	10%	40%
urban_sur_th	None	10%
orog_diff	Typically, “orog_diff” = 100 m, but some cities require higher limits Typically, “sftlf_th” = 70%, but some cities require lower values to include any urban cell (see YAML file)
sftlf_th
min_city_size	See YAML file
ratio_r2u	2
