'This is a very important book for anyone interested in understanding the climates of cities - their characteristics, controls, causes and implications. Comprehensive, clearly written, richly illustrated, and with broad ranging examples and well documented sources of data, this is a book that should be read by researchers, students and practitioners interested in the urban environment, urban planning and design, and smart cities. Its presentation makes it accessible, valuable and insightful, to those new to the field as well as established experts. This book will be a classic reference that will stand up to being read many times.' Sue Grimmond, University of Reading
