Daytime concentrations of HONO, NOx, OH and photolysis frequencies were measured during the ECHO field campaign in a mixed deciduous forest near Julich, West-Germany, in summer 2003. Midday measurements show clear evidence for a large, yet unexplaine

Reactions of ozone with alkenes can be a significant source of hydroxyl radicals in the atmosphere. In the present paper, the formation of OH radicals in the ozonolysis of selected alkenes under atmospheric conditions was directly observed. The exper

Room-temperature rate constants for the removal of OH radicals in the gas-phase reaction with acetylene have been determined using pulsed H2O2 photolysis production of OH followed by cw UV-laser long-path absorption detection. The pressure dependence
