Spatial proxies for UrbEm

Raster datasets to be used with UrbEm v1.0 (https://github.com/martinottopaul/UrbEm).

This collection of raster datasets is based on products by Copernicus Land Monitoring Service, the European Pollutant Release and Transfer Register as well as the Urban Centre dataset by the Global Human Settlement Layer provided by the EC.

These datasets have been prepared, merged and edited to be applied with the Urban Emission downscaling tool UrbEm (doi) to create urban-scale emissions for air quality modeling as described in Ramacher et al. 2020 (doi).
