§If the SM initial conditions
are set correct and the downward solar radiation is increased by 20%, then surface soil moisture simulations are not
affected very significantly.
§If observation
error variance is significantly higher than model error variance, EKF data assimilation may not be affected by observation. A correct assimilation of the observation is associated
with a correct estimate of the observation error variance.

Obs Error Variance Impact
Top layer soil
moisture from TMI data assimilaton experiments where model
forcing and obs error variance are set differently
