Short summary
Snow density plays an important role in natural and human systems but current methods for estimating snow density are limited, especially in the Arctic. This work presents a new method using satellite data to estimate snow density in remote areas. An experiment was conducted in the Canadian Arctic to evaluate the algorithm and it appears to replicate density estimates from manual sampling well. With more work this algorithm could be applied to estimate snow density across the pan-Arctic.
