Dr. Huemmrich has developed and used models of light interactions with vegetation, and has studied the use of remotely sensed data to collect information on biophysical variables and land cover type using both computer models and field measurements. He is familiar with bi-directional and hyperspectral data and their uses in determining biophysical characteristics. He has been involved in the analysis of remotely sensed data from a variety of platforms, including data collected from surface, aircraft, and satellite instruments.
He has experience in collecting data on biophysical variables in the field, with direct experience with both broad band and hyperspectral radiometers to determine vegetation canopy spectral reflectance, measured leaf level reflectance and transmittance using an integration sphere, measured light transmittance of vegetation canopies and their leaf area index. He has performed fieldwork on the use of remote sensing in a variety of habitats, including the tundra, desert, shrubland, tall grass prairie, agricultural fields, boreal forest, temperate rain forest, and temperate deciduous forest. Dr. Huemmrich was involved in the operations and data analysis for the Boreal Ecosystem and Atmosphere Study (BOREAS) and the First International Satellite Land Surface Climatology Project Field Experiment (FIFE) in Kansas. He was the assistant Information Scientist on these experiments, in particular working directly with the archival of the flux tower data, and has experience in the development and operation of interdisciplinary information systems in support of large field experiments.
