Abstract	:	Falling snow is an important component of global precipitation in extratropical re-gions. This study describes the methodology and results of physically based retrievalsof snow falling over land surfaces. Because microwave emitted by snow-covered sur-faces are highly variable, precipitating snow above such surfaces is difficult to observeusing window channels that occur at low frequencies (v < 100 GHz)). Furthermore,at frequencies v < 37 GHz, sensitivity to liquid hydrometeors is dominant. Theseproblems are mitigated a t high frequencies (v > 100 GHz) where water vapor screensthe surface emission, and sensitivity to frozen hydrometeors is significant. However,the scattering effect of snowfall in the atmosphere at those higher frequencies is alsoimpacted by water vapor and supercooled water in the upper atmosphere....,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
