The Airborne Tropospheric Hydrogen Oxides Sensor (ATHOS) is an in situ airborne sensor developed by Penn State University. ATHOS uses laser-induced fluorescence (LIF) to measure hydroxide (OH) and hydroperoxyl (HO2) in the atmosphere. ATHOS operates near 308 nm, has a pulse repetition frequency of 3 kHz, and a typical time resolution of 20-30 seconds. It was designed for installation on NASA’s DC-8 aircraft and can collect measurements of OH and HO2 under clear-sky and light-cloud conditions.
