Abstract: Remote sensing advancements in recent years have enabled monitoring of the Earth's land surface with unprecedented scale and frequency. In the past decades, remote sensing observations of the land surface have become available from a number of satellite instruments and platforms including soil moisture, snow depth, snow cover, terrestrial water storage, vegetation, and land surface temperature. To support the effective exploitation of the information content of the remote sensing observations, computational tools such as data assimilation are necessary. In this talk, efforts towards the concurrent use of all available remote sensing observations in a multivariate data assimilation configuration using the NASA Land Information System (LIS) will be presented. In addition to describing the advances made towards the effective utilization of remote sensing data for hydrologic prediction, some of the challenges and gaps that remain will also be discussed.
