Impacts of topographic shading on direct solar radiation for valley glaciers in complex topography

TopoSol – Topographic forcing for clear-sky direct solar radiation Matthew Olson

Short summary
Solar radiation is the largest energy input for most alpine glaciers. However, many models oversimplify the influence of topographic shading. Also, no systematic studies have explored the variable impact of shading on glacier ice. We find that shading can significantly impact modeled solar radiation, particularly at low elevations, at high latitudes, and for glaciers with a north/south orientation. Excluding the effects of shading will overestimate modeled solar radiation for alpine glaciers.
