Description

This dataset provides the concentrations of hydrogen oxides measured by the Airborne Tropospheric Hydrogen Oxides Sensor (ATHOS) during airborne campaigns conducted by NASA's Atmospheric Tomography (ATom) mission from 2016 - 2018. ATHOS uses laser-induced fluorescence (LIF) to measure hydroxide (OH) and hydroperoxyl (HO2) simultaneously. The measurements include OH and HO2 mixing ratio in parts-per-trillion-by-volume (pptv), OH interference from chemical removal in pptv, and OH reactivity from discharge flow in hertz.
