The map shows the average soil sealing degree inside the UMZ of European core cities (core city defined in Urban Atlas / Urban Audit). Soil sealing degrees are represented in coloured dots. The city dots are overlaid onto a modelled map displaying the change in annual number of days with heavy rainfall between the reference periods 1961-1990 and 2071-2100.
