Descriptive Micrometeorology compiles views and findings in micrometeorology, which is concerned with the surface boundary layer or thin slice of atmosphere extending from the ground up to a height of approximately 50 meters. This book describes the micrometeorology of soil, short vegetation, forest, water, ice, snow, and built-up urban surfaces. The properties and influence of the planetary boundary layer are not included. The topics discussed include the energy balance at the earth-atmosphere boundary, radiative flux divergence, factors influencing air temperatures, and Kolmogorov similarity theory. The Eddy correlation method for measuring evaporation, radiation balance of snow and ice surfaces, heat storage and horizontal advection in water, and changes in wind patterns are also covered. This publication is intended for meteorologists, but is also a good reference for chemists, engineers, geographers, botanists, hydrologists, health physicists, glaciologists, town planners, limnologists, oceanographers, air pollution control officers, foresters, and ecologists interested in the surface boundary layer.
