A Virtual Issue on Air Quality Monitoring and Modeling Journal of the Air & Waste Management Association

Journal of the Air & Waste Management Association

Since the inception of the U.S. Clean Air Act, great strides have been made in improving air quality in the United States. However, across the globe, elevated levels of nitrogen deposition, ground-level ozone, fine particulate matter, and other toxic air contaminants continue to be a problem adversely affecting human health and the environment. In combination with climate change, we require transdisciplinary research and decision-making to better understand and effectively manage the complex interactions of atmospheric pollutants on human health and the environment.

Science and technology must continue to play an active and decisive role in the development and implementation of air pollution control policies. There are numerous advanced scientific tools to assist in such policy development. Air monitoring is the most effective tool for identifying not only the magnitude and extent of air quality problems, but also ensuring compliance with the regulatory standards. Observations help build air quality models and are used to conduct model performance evaluations. However, air monitoring, especially for multiple pollutants over large geographical areas, is expensive. Air quality models are often used to supplement measurements or to provide estimates of pollutant concentrations at a high spatial resolution over a large area. Models can also help to resolve the issues presented by pollutant mixtures or complex interactions between air pollution and climate change, and are useful tools for air quality management decisions.

I invite you to read the papers on air pollution monitoring and air quality modeling included in this Virtual Issue. I also encourage you to read the peer-reviewed papers on air pollution and waste management published in the current and upcoming issues of JA&WMA, one of the oldest continuously published, peer-reviewed, technical environmental journals in the world.
