The campaign Chemistry of the Atmosphere Field Experiment (CAFE) Brazil was conducted in the Amazon rainforest in December 2022 and January 2023 to study new particle formation in the outflow of convective systems over the Amazon rainforest. In the f

Nitrogen oxides ( NO x ≡ NO + NO 2 ) are centrally involved in the photochemical processes taking place in the Earth's atmosphere. Measurements of NO2 , particularly in remote areas where concentrations are of the order of parts per trillion by vol

Mechanisms of tropospheric ozone (O3) formation are generally well understood. However, studies reporting on net ozone production rates (NOPRs) directly derived from in situ observations are challenging and are sparse in number. To analyze the role o
