Measurement report: Development of a portable peroxy radical measurement system and application for diagnosing local ozone formation and transport

Abstract. Atmospheric total peroxy radicals RO2* (RO2∗=HO2+∑RO2) play central roles in tropospheric chemistry, governing the formation of ozone and secondary aerosols. However, due to their extremely low concentrations and high reactivity, direct observation of RO2* remains chall...
