Where Water Meets Air: The Science of Surface Phenomena presents the current understanding of the water surface layer, integrating both experimental insights and theoretical developments. It also seeks to revisit and clarify some of the "known unknowns" that continue to challenge our knowledge of this interface. Some of the key points discussed in the book are as follows:Clarifies the uncertainty in predicting how water influences the greenhouse effect and climate changePresents complex scientific ideas in a clear, easy-to-follow style, making it valuable for both non-experts and specialists seeking a concise overviewIntegrates mathematical models with graphical illustrations to enhance understanding and bridge theory with real-world observationsRevisits and explains the relevance of landmark scientific concepts and debates that continue to shape our understanding todayThis book will benefit postgraduates, senior undergraduates, graduate students, and academic researchers in environmental science and engineering, chemical engineering, surface engineering and fluid mechanics.
