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.
