Potential topographic radiation enjoyment (25 m grid data) (WMS service)

The potential topographic radiation enjoyment or the global radiation indicates the amount of energy in KWh/m² that hits directly on the Earth’s surface in one year at a location. The solar constant of 1367 w/m² and a transmission rate (reduced permeability of the atmosphere due to clouding influence) are assumed to be 60 % (60 % = approx. average value for Germany). Dispersions are not taken into account. Due to shading (Sky View Factor), slope inclination and exposure, the global radiation of a site varies. This complex relief parameter goes beyond parameters such as sun and shadehang or a classification of exposure. Böhner, J., & Antonic, O. (2009). Land-Surface Parameters Specific to Topo-Climatology.
