•How can we evaluate the soil
moisture assimilation?
•Soil moisture – ideal but limited data available. United
states has 19 stations
in Illinois, 6 stations in Iowa and transect of 89 points in New Mexico for SMMR
period.
•Analysis increments – only provides check for
systematic biases.
•Runoff - data available but assumes that soil moisture is the only reason for poor estimates.
•Evapotranspiration – data not available and assumes
that soil moisture is the
only reason for poor estimates.
•Precipitation forecasts – assumes soil moisture is the only reason for poor forecasts.
