Session A08: Megacities Air Pollution: Urban, Regional and Global Impacts

During the next three decades, the world population is expected to increase from 6.1 billion to 8.1 billion, with nearly all of this growth concentrated in urban areas. Many of these urban centers are expanding rapidly, leading to the growth of megacities, which are often defined as metropolitan areas with populations exceeding 10 million inhabitants. These concentrations of people and activity are exerting increasing stress on the natural environment, with impacts at urban, regional and global levels. In recent decades, air pollution has become one of the most important problems of megacities and has serious impacts on public health, causes urban and regional haze, and has the potential to contribute significantly to climate change. Participants in this session will present atmospheric science studies conducted in megacities around the world, highlighting the following areas: 1. Emissions; 2. Meteorological measurements; 3. Particle and trace gas measurements; 4. Satellite observation; 5. Photochemistry; 6. Dynamics and radiative effects; 7. Air quality modeling; 8. Policy implications of reductions in emissions; 9. Health Effects.
