Description
This dataset contains branch-level emissions emission factors, total ozone reactivity, and related data from sweetgum, white oak, and loblolly pine during the Southeast Oxidant and Aerosol Study (SOAS) campaign at the SEARCH facility near Centerville (SEARCH-CRT) at the Alabama Aquatic Biodiversity Center (AABC) from May to July 2013.
