Ř Test another assimilation scheme which only updates total SWE (not SWE in each layer), but involve model dynamics in the estimation of state transition matrix (here it becomes a
scalar). The SWE, snow depth, and heat content are derived from the
geometrical relationship between snow layers, and utilizing estimated density
and temperature from model.
Ř Perform a numerical study on bias correction with respect to surface snow temperature and/or air
temperature. Investigate the utility of assimilating novel snow observation
products, such as snow melt
signature and fractional
snow cover.
Ř Assimilate real data. Specifically, SWE measured by
passive microwave measurement from satellites in the North America,
specifically those measurements taken over the past 20 years from SSMR and SSM/I.
This study may be expanded over the whole globe.
