General information and objectives

Scientific aims:
• To provide kinetic and mechanistic data for the detailed modelling of basic organic and N0x chemistry which influences ozone formation in the free troposphere.
• To formulate models describing the chemistry of more complex organic and N0x compounds occurring in the polluted boundary layer, and in air parcels transporting ozone precursors to the free troposphere.

Highlights of LACTOZ scientific results
The research undertaken by the 25 LACTOZ groups concerns reactive radicals in the atmosphere. For example, progress has been made in the knowledge of the oxidation of volatile organic compounds (VOCs), more specifically on the fate of peroxy radicals formed after the primary reaction of VOCs with OH radicals whose rates change markedly with the type of VOC. New data have also been produced on the first steps of the mechanism of the night-time NO3 initiated oxidation of VOC which is particularly efficient for alkenes.
LACTOZ groups have produced definitive publications on the chemistry of the nitrate radical (N03) and organic peroxy radicals, as well as detailed reaction schemes for day and night-time oxidation of VOCs together with nitrogen chemistry.
