Soil Moisture

Dr. DeLiberty has continued her dissertation work investigating the temporal and spatial variability of soil moisture initially focusing on Oklahoma and more recently across the Delmarva Peninsula.  Understanding the spatial and temporal nature of soil moisture and its persistence is vital in determining the influence that land surface processes have on the atmosphere, and is especially relevant to seasonal and long-term weather prediction.  DeLiberty’s focus on Oklahoma represents an ideal study area because of its diverse nature, both climatologically and physically. The two maps below illustrate the variability in vegetation and soil characteristics.

The Figure below illustrates the average seasonal soil moisture derived for the winter, spring, summer and fall seasons.  Please see the DeLiberty and Legates (2008) publication for more details.  

Soil Moisture

More recently, in collaboration with a geography graduate Ryan Ippolito, we examined the annual cycle and persistence of soil moisture across the Delmarva Peninsula from 2005-2008 using the Delaware Environmental Observing System (DEOS) network.The graph below displays the average conditions in Newark, Delaware for 2007.Soil moisture is represented as percent of volumetric water capacity.
