Soil Moisture Assimilation
Accurately initializing soil moisture can improve seasonal forecasts of streamflow and of mid-latitude summer precipitation and air temperature over land. Soil moisture impacts are mediated through land-atmosphere feedback and memory in root zone soil moisture anomalies. Skill in atmospheric forecasts stemming from land initialization demonstrates that such land-atmosphere feedback exists. Land data assimilation systems use numerical land surface models along with observations of soil moisture and precipitation to provide enhanced estimates of soil moisture conditions.
