Tracy DeLiberty




My research interests are in the areas of physical and hydroclimatology, GIS and remote sensing focusing one 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 area I have investigated include the Southern Great Plains with my dissertation soil moisture work, the Amazon Basin and more recently the Southern Ocean examining sea ice thickness.
