Page 2 - The use of climatology to predict air quality is based on the assumption that the past is a good predictor of the future.
Page 15 - Aerosols participate in a variety of chemical and physical processes in the troposphere. On a regional scale, these processes are associated with regional air quality as related to visibility and the effects of fine particles on human health. In this regard, there is a natural synergism between pollutants like ozone and sulfur dioxide and fine particles.
Page 15 - Nitrogen oxide and VOC emissions continue to react with ozone at night, leading to additional reactions involving the nitrate radical. These processes can significantly affect the reactivity and concentration of the pollutant mix that populates the atmosphere during the next diurnal cycle.
Page 14 - Because of the important role that photochemistry plays in the formation of ozone and other secondary air pollutants, the vast majority of the intensive atmospheric process studies conducted to date have focused on the daylight hours. Analysis of data...
Page 15 - With this in mind, new research is needed to elucidate: • how chemical processing on aerosols influences ozone formation • how the atmospheric oxidation leading to ozone formation leads to aerosol formation • how atmospheric chemistry influences the growth and chemical composition of aerosols.
Page 8 - EPA's Environmental Monitoring for Public Access and Community Tracking (EMPACT) Program. The...
