Tracy DeLiberty

Graduate GIS Certificate Director and Associate Professor

Biosketch

My research interests are in the areas of physical and hydroclimatology, GIS and remote sensing focusing on land surface interactions with climate (and vice versa) by investigating regional to global observations and remotely sensed datasets.  I rely heavily on using GIS and image processing systems for visualization of the geographic data and for mapping and spatial analysis.  Geographic areas I have investigated include the Southern Great Plains with my dissertation soil moisture work, the Amazon Basin and more recently the polar oceans examining sea ice thickness.

Current Projects

Sea Ice Thickness - With funding initially from the National Science Foundation (NSF) and several National Ice Center (NIC) grants, Dr. DeLiberty has been instrumental in converting paper ice charts to usable digital geographic databases for investigating sea ice thickness and volume in the Southern Ocean. Read More

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.

Thermal Remote Sensing - In collaboration with Dr. Thomas McKenna and a graduate student Lillian Wang, this study evaluated the use of thermal satellite imagery to locate and delineate ground water discharge areas in the Inland Bays using Landsat ETM+ imagery. Read More
