Dr. T. N. Carlson, Ph.D., Imperial College, University of London, is a Professor of Meteorology at the Penn State University and an adjunct member of the Environmental Institute, College of Earth and Mineral Sciences. Professor Carlson’s scientific contributions, approximately 90 papers published in refereed journals, reflect a wide range of interests, as indicated in the reference list below: synoptic and dynamic meteorology, radiative transfer, severe local storms, plant-atmosphere interactions, aerosol transport and chemistry, remote sensing of land surface properties and surface energy processes, and, most recently, applications of remote sensing to the study of urban sprawl and small watershed runoff. In 1991 Professor Carlson published a widely used book on meteorology (Mid Latitude Weather Systems). Recently, he has created two new web products related to his current interest in land surface processes: a course in Land Surface Processes (“Simsphere”) and a data base of impervious surface area and fractional vegetation cover determined from Landsat 5 digital imagery at 25 m resolution for all of Pennsylvania, 1986 and 2000 (to be found at the PASDA site); he is currently working with others to implement a web-based tool which will allow interested members of the public to assess the health (nutrient load) of a user-defined stream basin. Professor Carlson’s unique area of expertise also extends to developing methods to estimate surface energy fluxes (heat and moisture) from satellite. He has published a highly useful and accurate method of estimating evapotrasnpiration from satellite, the so-called ‘triangle’ method, currently being used by other investigators. He is one of the few physical scientists who has used an urban growth model, whose function was to estimate land use and surface hydrology changes in watersheds.
