Data sets

Data from experiment at RH = 50 % (α-pinene / OH, α-pinene / NO3, limonene / OH, limonene / NO3, cresol / NO3) EUROCHAMP https://data.eurochamp.org/data-access/chamber-experiments/#/

Short summary

This study investigates secondary organic aerosol (SOA) formation and particle growth from α-pinene, limonene, and m-cresol oxidation through NO₃ and OH radicals and the effect of relative humidity. The formed SOA is comprehensively characterized with respect to the content of OC / EC, WSOC, SOA-bound peroxides, and SOA marker compounds. The findings present new insights and implications of nighttime chemistry, which can form SOA more efficiently than OH radical reaction during daytime.
