Or limiting the availability of liquid water on the aerosol surface (e.g., Thornton and Abbatt, 2005 Anttila et al., 2006 Cosman et al.,Ģ008 Gaston et al., 2014). N 2O 5 uptake by inhibiting the mass accommodation of N 2O 5 Negate the nitrate suppression effect (e.g., Behnke et al., 1997 īertram and Thornton, 2009). With the intermediate H 2 ONO 2 + faster than NO 3 - and On the contrary, chloride in the aqueous aerosol will react Suppress the N 2O 5 uptake (e.g., Wahner et al., 1998 Bertram and ![]() The hydrolysis of N 2O 5 (e.g., Hallquist et al., 2003 Thornton etĪl., 2003), while nitrate favors the reverse of Reaction (R2) and thus The aerosol water content can enhance the N 2O 5 uptake by promoting To be dependent on aerosol chemical compositions such as water content, nitrateĬoncentration, chloride concentration, and organic coatings. γ N 2 O 5 wasįirst measured using aerosol flow tubes in the laboratory, and it was shown Γ N 2 O 5, is the fraction of N 2O 5 net removal uponĬollisions on aerosols, and it is a key parameter to describe the heterogeneous The reaction probability of N 2O 5, the so-called uptake coefficient HNO 3 or ClNO 2, respectively (Reactions R3 and R4) (Behnke et al., 1997 Finlayson-Pitts et al., 1989 Schweitzer et al., 1998 Thornton and Abbatt, 2005 Bertram and Thornton, 2009). H 2 ONO 2 + will react with H 2O or Cl − to form H 2 ONO 2 + in the aqueous phase (Reaction R2). Mass accommodation of N 2O 5 on aerosol surface (Reaction R1), followed by reversible N 2O 5 hydrolysis to form nitrate and intermediate Heterogeneous reaction of N 2O 5 on aqueous aerosols starts with the Realistically representing this process in air quality models is therefore necessary for the prediction and mitigation of ground-level ozoneĪnd particulate pollution. ( NO x), secondary nitrate formation, and chlorine activation through nitryl chloride ( ClNO 2) production on chloride-containing aerosols (Brown et al., 2006 Osthoff et al., 2008 Thornton et al., 2010 Wang et al., 2016). Surfaces plays an important role in the nocturnal removal of nitrogen oxides Heterogeneous reaction of dinitrogen pentoxide ( N 2O 5) on aerosol Nitrogen oxides, and secondary nitrate in the polluted regions of China. Incorporating this new parameterization into a regionalĪir quality model (WRF-CMAQ) has improved the simulation of N 2O 5, Work, which better reproduced the mean value and variability of the observed ![]() Significant discrepancies were found between the measured γ N 2 O 5 and that estimated from laboratory-determined parameterizations.Īn observation-based empirical parameterization was derived in the present Generally promoted by the aerosol water content and suppressed by particle ![]() The field-derived or measured γ N 2 O 5 was N 2O 5 uptake and the influencing factors under various climatic andĬhemical conditions. Previous field studies in China to obtain a holistic picture of Results were analyzed together with the γ N 2 O 5 derived from With an in situĪerosol flow-tube system, the γ N 2 O 5 was directly measured onĪmbient aerosols at two rural sites in northern and southern China. Accurate measurement of its uptakeĬoefficient ( γ N 2 O 5 ) and representation in air quality modelsĪre challenging, especially in the polluted environment. She also discovers that her close online friend, "L Jun" is the same person as famous author, Zhou Chuan.Heterogeneous reactivity of N 2O 5 on aerosols isĪ critical parameter in assessing NO x fate, nitrate production, and Chu Li overcomes the obstacles in her career, and finally becomes an established editor. At the same time, she also helps authors who are at their bottleneck stage find new inspiration, and with her unique vision, discover new potential authors. With her sincerity and professionalism, she earned the respect of reknowned authors and became their exclusive editor. As a newcomer editor, Chu Li sticks to her original aspirations, wholeheartedly dedicating to helping authors refine their works and publish high quality books. She was shocked to find out that the publishing industry at this time has underwent huge changes. However, a challenging path lies ahead of her. ![]() After graduating from university, with a passion for publishing, Chu Li successfully entered her dream company, Yuan Yue Publishing House.
