AB: The Advanced Microwave Scanning Radiometer - EOS (AMSR-E) instrument aboard NASA's Aqua satellite mission is used to estimate daily, five day maximum and monthly average snow water equivalent on a polar projected 25 x 25 km grid. The five-day and monthly products are based on the daily product which uses microwave brightness temperature observations at 10, 18, 36 and 89 GHz, two MODIS land cover products and a snow density "climatology" based on Russian and Canadian data. The current version (B07) of the product implements a dynamic algorithm that has developed from a static approach based on a method by Chang et al. (1987). Retrievals are performed at the native spatial resolution to reflect the measurement "process". This paper describes validation and algorithm developments to the product based on an assessment of the B07 version. New developments to the algorithm that improve the detection capability and that better correct for vegetation are described. The paper also identifies a pathway that will enable the product to reach level 1 validation status.
