Isoprene and monoterpene fluxes from Central Amazonian rainforest inferred from...
Kühn, Uwe; Andreae, Meinrat O.; Ammann, Christoph; Araüjo, Alessandro Carioca de; Brancaleoni, Enzo; Ciccioli, Paolo; Dindorf, TamaraWe estimated the isoprene and monoterpene source strengths of a pristine tropical forest north of Manaus in the central Amazon Basin using three different micrometeorological flux measurement approaches. During the early dry season campaign of the Cooperative LBA Air-borne Regional Experiment (LBA-CLAIRE-2001), a tower-based surface layer gradient (SLG) technique was applied simultaneously with a relaxed eddy a...
Monoterpene chemical speciation in a tropical rainforest:variation with season,...
Yáñez-Serrano, Ana Maria; Nölscher, Anke C.; Bourtsoukidis, Efstratios; Alves, Eliane Gomes; Ganzeveld, Laurens N.; Bonn, Boris; Wolff, StefanSpeciated monoterpene measurements in rainforest air are scarce, but they are essential for understanding the contribution of these compounds to the overall reactivity of volatile organic compound (VOC) emissions towards the main atmospheric oxidants, such as hydroxyl radicals (OH), ozone (O3) and nitrate radicals (NO3). In this study, we present the chemical speciation of gas-phase monoterpenes measured in the...
