Meteorological and Air Quality Models for Urban Areas

This book, based on the selected presentations given at the COST728 workshop, is concerned with the following main topics/chapters:

1. Urban morphology and databases,

2. Parameterisations of urban canopy,

3. Strategy for urbanization of different types of models,

4. Evaluation and city case studies / field studies.

The chapters were concerned with dynamic (on wind and turbulent) and thermal effects (on temperature and energy in general). The final chapter of this volume summarizes the discussion and conclusions from the four main topics and provides recommendations and future requirements.

The book is oriented towards numerical weather prediction and air quality modelling communities.

Résumé

This book for the first time gives an overall view of the current situation in urbanization of meteorological and air quality models around the world. It discusses and makes recommendations on the best practice and strategy for urbanization of different types of meteorological and air quality models.

Based on the selected presentations given at the COST728 workshop, the contributions are arranged in four parts: urban morphology and databases; parameterizations of urban canopy; strategy for urbanization of different types of models; and evaluation and city case studies / field studies. The chapters treat either dynamic (on wind and turbulent) and thermal effects (on temperature and energy in general). The final chapter of this volume summarizes the discussion and conclusions from the four main topics and provides recommendations and future requirements.

This monograph is oriented towards numerical weather prediction and air quality modelling communities.
