During RONOCO (ROle of Nighttime chemistry in controlling the Oxidising Capacity) campaigns (summer 2010 and winter 2011) a comprehensive group of NOy (NO, NO2, HNO3, total peroxy nitrates (ΣRO2NO2), total alkyl nitrates (ΣRONO2), N2O5 NO3, PAN) were measured on board the FAAM aircraft BAe-146. A diurnal flight (B548 – 03/09/2010) is studied in order to investigate the net production of Ozone and Alkyl nitrates in the London urban plumes. The analysis shows two regions, over London, characterized by different dependence between the Ox and the ΣANs, photochemical air masses age and dependence between NOx and aerosol nitrates. Here will be show the chemical mechanisms that can explain the observations in the two London areas.

Abstract

During RONOCO (ROle of Nighttime chemistry in controlling the Oxidising Capacity) campaigns (summer 2010 and winter 2011) a comprehensive group of NOy (NO, NO2, HNO3, total peroxy nitrates (ΣRO2NO2), total alkyl nitrates (ΣRONO2), N2O5 NO3, PAN) were measured on board the FAAM aircraft BAe-146. A diurnal flight (B548 – 03/09/2010) is studied in order to investigate the net production of Ozone and Alkyl nitrates in the London urban plumes. The analysis shows two regions, over London, characterized by different dependence between the Ox and the ΣANs, photochemical air masses age and dependence between NOx and aerosol nitrates. Here will be show the chemical mechanisms that can explain the observations in the two London areas.
