Claude Duguay - Professor - My research interests include the extraction of geophysical parameters from optical and microwave imagery, the development and improvement of numerical ice growth and heat transfer models, and the study of climate variability and change using lake ice and snow as indicators. Recent field, remote sensing and modeling studies have been in northern Canada (Quebec, Manitoba, Northwest Territories and Yukon Territory) and Alaska. Some of my recent and ongoing work include: the development and validation of remote sensing methods for mapping and monitoring lake ice and snow parameters, seasonally frozen ground, thaw lakes, as well as the radiation and energy balance of open forest and tundra surfaces; the development of a numerical model for simulating lake ice growth for lakes of various sizes under present and future climates; the development of a historical database for analyzing the response of lake ice to climate variability and change in Canada; field, remote sensing, and numerical modeling experiments to acquire a detailed understanding of and simulate and forecast the role of lakes in the energy and water-balance of Arctic river basins. http://www.gi.alaska.edu/~duguay back to People |
