Course Description
This course describes the physical environment (light, wind, temperature, humidity) about plants and the soil, how the physical environment affects the physiological status plants and how plants affect their physical environment. This course accomplishes its goals by examining the physical, biological and chemical processes that affect the transfer of momentum, energy and material (water, CO2, and atmospheric trace gases) between vegetation and the atmosphere. Instrumentation and measurements, associated with the study of plant biometeorology, are also discussed.
Course Schedule and Student Involvement
The class will meet three times per week (MWF 11-12) at 306 Wellman Hall. Hour lectures will be presented. Discussion and questions by the class is encouraged.
Class assignments will include readings from the Instructor's web-based lecture notes. Periodic homework assignments will involve accessing data from experiments that are posted on the World Wide Web and plotting them to discover mechanisms and relationships between plants and the atmosphere. One source of data for assignments is the FLUXNET web page (Fluxnet Web page); scientists, from throughout the world are posting their data on canopy microclimate and mass and energy fluxes. Other homework assignments will involve numerical calculations and solving problem sets. A term paper (8 to 10 pages) is assigned and due the 14th week of the semester.
