the surface to 1 m depth) data measured at the SCAN network over the Mississippi
Delta Region have been analyzed. Two-year time series of soil moisture daily
data from twelve SCAN sites located within 2.5x2.5 latitude-
longitude box were used for the temporal and spatial analysis.
The main objective of this analysis was two-fold. First goal
was to identify temporal and spatial peculiarities (such as typical local
wetting/drying rates and depths reflecting a capability of the soil "memory")
of soil moisture distribution at various SCAN sites. The second one was to associate
these peculiarities with control parameters/factors from the soil-landscape-atmosphere
continuum. The following factors were considered: precipitation, solar
radiation at the surface, water table, and soil texture and its variation with depth.
This study will be helpful for interpretation and reconciling frequently observed
differences/biases between soil moisture simulated by land surface models and
that of measured.
