Summary

In C04, we aim to improve continental-scale snow estimates in land surface model which often bear uncertainties due to both input data and model errors. For this purpose, we will develop and implement a multi-scale, multi-sensor snow data assimilation scheme in the fully coupled terrestrial systems modeling platform. This will be implemented by jointly assimilating the remote sensing snow observation such as snow cover fraction and snow water equivalent into the community land model (CLM). Further, we will assess the impact of snow data assimilation on surface energy states and fluxes for fully coupled land-atmosphere simulations.
