Description
Explores ecosystem responses to global environmental changes and how they feedback on the earth system. Students will learn about biophysical controls on energy, water, and carbon cycles, and how biogeography, vegetation physiology, and local to global climates influence surface-atmosphere exchanges, which then feedback on biogeography and climate. The course introduces the theory, remote sensing, and computational modeling of biophysical, biogeochemical, and ecosystem dynamical processes active in shaping the terrestrial biosphere. Students will be exposed to methods of land surface and ecosystem process modeling through computer tutorials with numerical simulation, and will train some basics of writing computer code. Can fulfill the Geography or Earth System Science Capstone.
