Importance of this Unit to the Course
Soil and vegetation interact with the
atmosphere (the atmosphere affects them and they, in turn, affect the atmosphere) in
complicated but important ways that ultimately determine the heating and cooling of the lower
atmosphere and the evaporation rate. These heating, cooling and moistening rates are
critical inputs to global and regional climate models and are provided by
soil-vegetation-atmosphere models.
Objectives
Preparation for Discussion (You must complete this section before class.)
Discussion
(online / face-to-face)
(See your portfolio for due dates and times)
A major component of the course is participation in the online dialog.
The following types of comments are required:
By examining seasonal differences in earth surface cover between Jan-Feb and Jul-Aug what are some key factors that need to be considered in representing the albedo (reflectivity) of the earth's surface in soil-vegetation-atmosphere models?
