This study presents several sensitivity studies on the assimilating of different microwave signals into a dual-pass land data assimilation system to improve near-surface soil moisture estimation. Investigated are different polarizations, over pass time, and frequency combinations of AMSR-E brightness temperatures. Results shows that the vertically polarized, nighttime signals are the optimal choice in current system. In addition, a simple frequency-based ensamble estimation can produce more robust estimate when using different forcing data.
