Spectroscopy and radiative transfer are rapidly growing fields within atmospheric and planetary science with implications on various fields. Remote sensing and modeling atmospheric composition require detailed knowledge of how radiation and matter interact in planetary atmospheres. This book provides this fundamental knowledge to a depth that will leave a student with the background to become capable of performing quantitative research on atmospheres. The book is intended for graduate students or for advanced undergraduates. It spans across principles through applications, with sufficient background for students without prior experience in either spectroscopy or radiative transfer. Courses based on this book are intended to be accompanied by the development of increasing sophisticated atmospheric and spectroscopic modeling capability (ideally, the student develops a computer model for simulation of atmospheric spectra from microwave through ultraviolet).-- Source other than Library of Congress.
