The result is a concise course in atmospheric radiative processes, tailored for one semester. The authors are accomplished researchers who know how to reach their intended audience and provide here the content needed to understand climate warming and remote sensing for pollution measurement. They also include supplementary reading for planet scientists and problems.
Equally suitable reading for geophysicists, physical chemists, astronomers, environmental chemists and spectroscopists.
A solutions manual for lecturers will be provided on www.wileyvch.de/supplements.
