SwissRad10 Hourly light availability maps at 10 m resolution over Switzerland

Areas below and within 25 m of forests include light availability calculated for both leaf-on and leaf-off canopy structure, and terrain only data is available across the full domain. The variables sky-view fraction and direct-beam transmissivity are both included, allowing estimation of both direct and diffuse light at the ground surface.

The dataset was calculated using the detailed synthetic hemispheric image-based ray-tracing Canopy Radiation Model (CanRad) with the latest airborne lidar and terrain surface data from the swissSURFACE3D dataset.
