Date & Time: Feb 18 2026 | 12 - 1pm Location: iSTEM Building 2, Room 1218 Tropospheric ozone is a major pollutant in many large urban areas. Ozone is not emitted into the atmosphere directly but instead is formed by reactions of gases that are emitted from a variety of sources. Volatile organic compound (VOCs) reaction rates with the hydroxyl radical can result in gases in the parts per trillion concentration range having significant impact on urban ozone production. Thus, it is essential to identify and quantify VOCs in urban areas so that pollution control officials can effectively regulate VOC sources. Results from Airborne and urban sampling during the past decade will be discussed in this seminar.
