- Abstract:
- Nitrate radicals (NO3) react with peroxy radicals (RO2) to generate hydroxyl radicals (OH), a hitherto unexpected source of OH at night. NO3 may thus play a pivotal role in the residual boundary layer at night, influencing both the production of HOx and the partitioning of NOy. Accurate modelling of these key atmospheric processes requires new laboratory data. The proposers previously studied reactions of NO3 with CH3O2, C2H5O2 and CH3COO2, but the kinetics and products of reactions with other types of RO2 (eg secondary, tertiary, allyl, etc) are unexplored. Our project seeks to remedy some of the deficiencies. Discharge-flow methods will be employed in the laboratory. New techniques now available for the detection of the radicals make this a particularly timely opportunity for an attack on the problem. The laboratory studies will be backed up by sophisticated modelling.
