Analysis reveals cost-effective snow monitoring via remote sensing and gamma-ray surveys with advanced unmanned aerial vehicles.
Ground-based monitoring of snow moisture content conducted in the Russian Federation in the 1960s was supplemented by remote sensing using two-stage (fall and spring) airborne gamma-ray surveys, which subsequently fell into disuse due to their high cost. During the same years, a significant modernization of remote snow monitoring was proposed, using single-flight gamma-ray surveys and later, unmanned aerial vehicles.
