Radiation and climate change FS 2014

Assignments

The aim of this course is to develop a thorough understanding of the fundamental role of radiation in the context of climate change.

This course consists of 2 contact hours per week (see Semesterprogramm), Friday 08:15h-10h in RZ F21. It is taught by Martin Wild.

The course covers the following topics:

Basic radiation laws; sun-earth relations; the sun as driver of climate change (faint sun paradox, Milankovic ice age theory, solar cycles); radiative forcings in the atmosphere: aerosol, water vapour, clouds; radiation balance of the Earth (satellite and surface observations, modeling approaches); anthropogenic perturbation of the Earth radiation balance: greenhouse gases and enhanced greenhouse effect, air pollution and global dimming; radiation-induced feedbacks in the climate system (water vapour feedback, snow albedo feedback); climate model scenarios under various radiative forcings.
