Abstract:
In the past few years there have been numerous studies about the assimilation of land surface observations, primarily of soil moisture and soil temperature, into land surface models that are not coupled to the atmosphere. I will present a few examples of these results, with a focus (1) on the choice of assimilation method and (2) on the ability to use data assimilation for downscaling from coarse scale satellite observations to finer scale hydrologic estimates, and (3) on the implications of the lessons learned for coupled land data assimilation.
