Soil Science Room 331 Undergraduate Teaching Environmental Science 1425 The Atmosphere: The goal of ES 1425 is to introduce the basic physical, chemical and biological processes that drive changes in Earth's weather and climate. Topics will include: radiation and energy exchange; greenhouse effect; stratospheric ozone depletion; severe weather hazards; general circulation of the atmosphere; climate teleconnections including El Ni?o, and impacts of human activities on climate. Weekly field and computer labs are used to investigate how weather and climate data are measured, analyzed and interpreted. All lecture and lab materials are made available on the course web site. Graduate Teaching Environmental Science 5402 Biometeorology: ES 5402 - examines energy and mass exchange in the biosphere with an emphasis on soil-plant-atmosphere interactions. Topics include: an introduction to boundary layer and turbulent exchange processes; measuring energy and trace gas exchange with eddy covariance, Bowen ratio and gradient techniques and, advanced methods combining stable isotope and micrometeorological measurements for studying the impacts of climate and land use change on carbon and water cycling. There is an emphasis on the use of boundary layer theory and techniques for studying ecophysiological processes, biosphere feedback mechanisms, and the interaction between the Earth's surface and the lower atmosphere. The course aims to achieve exemplary learning by examining recent field studies conducted in natural and managed ecosystems. Assignments/Projects will make use of field measurements and computer problem solving using Matlab. Lecture/Seminar/Lab (3 credits 2 hours class time/week). Grade: 20% participation; 40% assignments/project; 40% exam. |
