ABSTRACT. For over 25 years the IMPROVE network has been collecting speciated aerosol data with which to examine trends in aerosol composition and reconstructed haze. By analyzing trends we have observed dramatic widespread improvements in visibility through the reduction of pollutants and precursor emissions. However, analyses have also revealed that some regional and seasonal mean aerosol concentrations have increased, counter to reductions in known regional and local emissions. These positive regional trends point to the importance for understanding the influence of non-regulated sources and international contributions to particulate matter and visibility in remote areas of the United States.

Dr. Jenny Hand is a research scientist at the Cooperative Institute for Research in the Atmosphere at Colorado State University. She has been working on issues related to air quality and haze in national parks and remote areas for nearly 20 years. She currently serves as the Chair of AWMA’s visibility technical coordinating committee.
