Abstract:As a highly reactive dialkenes similar to isoprene, 1,3‐butadiene (BD) is rapidly oxidized and fully involved in atmospheric oxidation processes. We have established a method for the online measurement of ambient BD using Differential Optical Absorption Spectroscopy (DOAS) technique. Lab testing demonstrated that DOAS technique can accurately measure BD concentrations in high temporal resolution of minute‐level, with accuracy and precision within ±5% and 1%, respectively. Following field measurement, the detec… Show more
