Figure 1: 15-day EDAS precipitation accumulations, for (a) control run, (b) precipitation assimilation run, as compared to observed precipitation (c) (from RFC 24h observations) and the resulting impact on soil moisture ((d) and (e)) at the end of the 15-day period. Note how the excessive precipitation in the control run (a) in the southeast U.S. evidently led to very moist soil in that region, and how precipitation assimilation corrected for that problem.
