Transport and Diffusion in Turbulent Fields : Modelling and Measurements Techniques
The 35th OHOLO Conference, which provided the basis for the present book covered a broad range of topics. Basic studies and newly developed methods in modeling atmospheric flows are discussed, besides analyses of concentration fluctuations in different atmospheric conditions, and techniques of data acquisition. The book gives state-of-the-art impression of the situation in turbulent diffusion and transport.
