In the JULIAC campaign, ambient air was continuoulsy flowed with a high flow (residence time of air: 1 hour) through the chamber for 4 weeks in each season 2019. Gas-phase species, radicals and aerosol properties were measured with a large set of instruments. Data were analysed with respect to the production and destruction of radicals and ozone formation.
