Short summary
UV absorption and electrochemical O3 sensor measurement techniques suffer from interferences, especially from SO2, which is a main constituent of volcanic plumes. Only chemiluminescence (CL) O3 monitors have no known interference with SO2. However, modern CL O3 monitors are impractical because they are heavy and bulky. We developed and applied a lightweight version of a CL O3 instrument (l.5 kg, shoebox size) and present the result of those drone based CL O3 measurements.
