Theory on the exchange of energy and matter (carbon, water) between the land surface and atmosphere, with a focus on the implications of ecosystem-level processes for regional micrometeorology. Examples will be taken from research on contemporary as well as palaeoclimate systems. Case studies to include how changes in vegetation type alter surface radiation balance, hydrological cycling and heat transfer in soils. There is no formal textbook for this course. Lecture material will be augmented with assigned readings from the scientific literature.
