I took Mike's class at Harvard and found it fascinating. The book is thorough and extremely clear - when I first opened it I was intimidated by the number and complexity of some of the diagrams but all is explained in the book in short order. The chapters on climate change and urban ozone are particularly interesting. I think this book could easily be read even if you don't have a scientific bent by just skipping some of the more technical work - you don't need to understand the photolysis of ozone to understand smog. I don't know of any other text that applies to so well to a fairly broad audience.THe only group to whom I would not reccommend this book are serious grad-level atmospheric chemists. This would be a little infantile for that group.
