Data Assimilation of 10 GHz Brightness Temperatures into a Land Surface Model

Experimental Plan

•Control Run

–Mosaic LSM w/one tile/grid box

–LDAS forcing

–April 1st – Dec 31st, 1998

•Dry Run

–¼ the amount of precipitation

–All else the same as Control (incl. initial conditions)

•Dry Run w/Data Assimilation

–Kalman Filter w/TRMM soil moisture

–Daily assimilation (if obs. available)
