The present book is pitched at this level. It is aimed at the physicist rather than the mathe matician. The major theme is the parameter ization of radiation processes in a usable form for practicable problems, with particular emphasis on the rather difficult areas of radiation transfer in clouds and aerosols. The book aims to give a coherent account of radia tive processes in the atmosphere and their C.

Unfortunately, the modem literature on the subject has developed a certain mystique of its own and is not readily under stood by the non-specialist. Apart from the excellent books by Kondratyev, there is a sizeable gap between the single chapter on radiation to be found in a number of text-books on general meteorology and the elegant theoretical treatises on radiative transfer by Goody and by Chandrasekhar. The gap occurs at just the level required by experimental atmospheric physicists or by meteorologists seeking to take account of radiative processes in their models. The present book is pitched at this level. It is aimed at the physicist rather than the mathematician.
