Snow Assimilation

Snow influences climate through its higher albedo and emissivity, its ability to insulate the soil, and its utilization of energy for snowmelt and sublimation. The role of snow in climate variations is well documented in observational and modeling studies. For example, early season snow cover anomalies in Eurasia have been found to modulate wintertime climate variability in northern hemisphere mid-latitudes. Land data assimilation systems use numerical land surface models along with observations of snow and precipitation to provide enhanced estimates of snow conditions.
