Abstract
Sand dunes appearing in remotely-sensed imagery may be used measure and characterise valley wind regimes where meteorological observations are not available. In this study, a method for determining the direction and seasonality of valley winds using Sentinel satellite imagery is explained. The method - which includes the digitisation of dune ridges and construction of wind roses in QGIS, is applied to the Hunder dunefield in the Northern Himalaya where the prevailing wind direction, and seasonal variability in wind direction are identified. The results are then applied in a local land management context, to inform government spending on sand dune stabilisation projects in this region.
