This book is intended as a textbook for courses in micrometeorology for undergraduate students (juniors or seniors) in meteorology or environmental science, as well as for an introductory graduate-level course in boundary-layer meteorology. It will also serve as a good reference for professional meteorologists, environmental scientists and engineers, particularly those interested in problems of air pollution, atmospheric-biospheric interactions, wind-engineering and engineering meteorology.

The book outlines basic laws and concepts, before using qualitative descriptions to introduce more complex theories. This new edition is updated and expanded, as are the references. Each chapter features worked-through problems and exercises.
