‘Mesoscale Modelling for Meteorological and Air Pollution Applications’ combines the fundamental and practical aspects of mesoscale air pollution and meteorological modelling. Providing an overview of the fundamental concepts of air pollution and meteorological modelling, including parameterization of key unresolved processes, the book also considers equally important aspects such as model integration, evaluation concepts, performance evaluation, policy relevance and user training. An adequate representation of the processes in the boundary layer is crucial for numerical modelling of the weather, air pollution and atmospheric dispersion. This has led to the development of a multitude of parameterizations which attempt to fulfil the special needs of air pollution and atmospheric dispersion modelling. Efforts have been directed towards achieving greater sophistication in schemes and representing the physical processes more realistically through higher model grid resolution that has been made possible by the ever-increasing computer power. Therefore, the development and requirements for new parameterizations go hand in hand with the advances in computing capability.
