      Key Points

      • Passive microwave SWE estimates compare well to SNODAS in regions with less than 20% forest and no more than 200 mm SWE
      • In deep snow regions, passive microwave SWE estimates share the timing, but not the magnitude or rank-ordering of SNODAS
      • Algorithm differences between SSM/I and AMSR-E seem to account for dissimilar performance in areas with dense vegetation or thin snow
