Course Description

In this course we study the 'Breathing' of the Terrestrial Biosphere. This is accomplished by describes the physical environment (light, wind, temperature, humidity) about plants and the soil, by understanding how the physical environment affects the physiological status plants and how status and capacity of plants and the underying soil affect their physical environment. Hence, the nature of this course is very multi- and intra disciplinary, drawing on aspects of micrometeorology, soil physics, physiological ecology, ecosystem ecology and biogeochemistry. 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 1-2) at 306 Wellman Hall. Hour lectures will be presented. Discussion and questions by the class is encouraged.

Grading: 1000 pts

midterm I: 250 pt

midterm II: 250 pt

5 homework assignments, 250 pt (50 pts each)

Final: 250 pts

 

Class Lecture Material, Web Page and Figures

Attendence and Class Participation is strongly encouraged.

Pdf copies of lecture overheads and material that augments the lectures is available for downloading on a lecture by lecture basis from the following table.

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.
