Chemical and meteorological influences on the lifetime of NO<sub>3</sub> at a semirural mountain site during "PA…

Abstract. Through measurements of NO2, O3, and NO3 during the PARADE campaign (PArticles and RAdicals, Diel observations of mEchanisms of oxidation) in the German Taunus mountains we derive nighttime, steady state lifetimes (τss) of NO3 and N2O5. During some nights, high NO3 (~ 200 pptv) and N2O5 (~ 1 ppbv) mixing ratios are associated with values of τss that exceeded one hour for NO3 and three hours for N2O5 near the ground. Such long boundary layer lifetimes for NO3 and N2O5 are usually only encountered in very clean/unreactive air masses whereas the PARADE measurement site is impacted by both biogenic emissions from the surrounding forest and anthropogenic emissions from the nearby urban…

Through measurements of NO2, O3 and NO3 during the PARADE campaign (PArticles and RAdicals, Diel observations of mEchanisms of oxidation) in the German Taunus mountains we derive nighttime steady-state lifetimes (τss) of NO3 and N2O5. During some nights, high NO3 (∼ 200 pptv) and N2O5 (∼ 1 ppbv) mixing ratios were associated with values of τss that exceeded 1 h for NO3 and 3 h for N2O5 near the ground. Such long boundary-layer lifetimes for NO3 and N2O5 are usually only encountered in very clean/unreactive air masses, whereas the PARADE measurement site is impacted by both biogenic emissions from the surrounding forest and anthropogenic emissions from the nearby urbanised/industrialised cen…
