A52B:
Air Pollution in Urban Airsheds During Winter II

Submit an Abstract to this Session



Session ID#: 30874

Session Description:
Severe urban air pollution during the winter season is a well-known phenomenon and significant public health issue. So called wintertime “killer smog” events in the U.S. and Great Britain in the 1940’s and 1950’s brought particular public attention to air quality as a public health issue. Episodic winter pollution haze events continue to occur despite decades of investment in emissions controls. Such events are found globally, in the U.S., Europe, China and beyond, and they generate high levels of public interest and concern, including demands for local action. The scientific understanding required to implement effective mitigation strategies remains challenging due to the complex and often non-linear interplay between cold weather meteorology, emissions, atmospheric chemical mechanisms and aerosol thermodynamics. This session invites submissions from recent field, laboratory and modeling studies relevant to the current state of the science in winter air pollution.
