  • Photochemical ozone production rates at different TOR sites : the report from TOR task group 2b
    Volz-Thomas, A. ...
    The production of ozone in the troposphere is accomplished through a series of reactions reffered to as the ʺphotochemical smog mechanismʺ. Typical of this mechanism are reactions (R1) through to ... (R7), where an initial reaction between a hydrocarbon, RH, and an OH radical results in the production of two ▫$O_3 molecules and an aldehyde R'CHO or a ketone. All TOR sites, where appropriate data for PSS analysis are available, exhibit similar ozone formation rates, when normalized to the primary controlling factors, i.e. UV radiation and precursor concentration. Also, the results from the TOR sites are quite similar to those derived for a rural site in North America (Scotia, Pennsylvania [29]. The rates can be compared to those derived with eq. 9 from the concentrations of NO and peroxy radicals (HO_2 and its organic homologues, RO_2). Peroxy radical measurements were made at Schauinsland and at Izaña using the technique of matrix isolation and ESR spectroscopy.$▫
