Impacts of soot, ash, sand, and haze on snow albedo in Sierra Nevada, Spain

Snow covers are greatly affected by particles deposited on their surface. In this work, an experimental campaign was carried out in the Sierra Nevada (Granada, Spain). The optical effect of different contaminating particles on the snow covers was measured using a field spectroradiometric system comp...
