Abstract The Southeastern Aerosol Research and Characterization (SEARCH) air quality monitoring network is a long-term multi-pollutant effort addressing scientific and regulatory questions on ozone and its precursors, particulate matter mass and composition, mercury speciation and deposition, wet deposition of acidity and nutrients and atmospheric visibility. SEARCH was conceived in the early 1990s as part of the Southern Oxidants Study SCION network. The eight-site network of urban-rural pairs provides a comprehensive suite of measured meteorological, gaseous, and particulate phase chemicals.
SEARCH network monitoring activities at the 5 current sites will cease after 2016, with varying closure dates. The Birmingham, AL, site closed July 1, with Yorkville, AL, and Outlying Field, FL, closing October 1. Jefferson Street/Atlanta, GA, and Centreville, AL, will close January 1, 2017. This poster describes the remaining monitoring plans, closure, and upcoming activities. The physical filter archives created from mid-1998 to present will be maintained for some time, and selected studies will be performed with them. Collaborations with external researchers on the use of the archive are encouraged.
Additionally, the full SEARCH database though the end of operations will continue to be made publically available at http://www.atmospheric-research.com/public/index.html. We encourage its continued use by the research community. To date, SEARCH data have been the basis of approximately 270 peer-reviewed scientific publications and have been used to constrain and evaluate local, regional, continental and global-scale atmospheric models, assess atmospheric chemical and physical processes at hourly to decadal time resolution, perform source attribution, evaluate new instrumentation, assess the impact of upcoming regulations, and support investigations of human health impacts of air quality.
The authors are grateful for the long-standing support from Southern Company and EPRI, as well as the many collaborators that have made the SEARCH network a unique experience. We look forward to continued collaborations in the future.
