Effects of aerosols on tropospheric photolysis rates in clear and cloudy atmospheres
The effect of aerosols on 14 tropospheric photolysis reactions is examined under noncloudy and cloudy sky conditions by using a detailed one-dimensional radiative transfer model. Pure (NH4)2SO4, pure soot, and internal and external mixtures of the two aerosols, as well as mineral dust aerosol, are considered. Nonabsorbing aerosol generally enhances photolysis rates above and in the upper part o...
متن کاملInteractions between tropospheric chemistry and aerosols in a unified general circulation model
[1] A unified tropospheric chemistry-aerosol model has been developed within the Goddard Institute for Space Studies general circulation model (GCM). The model includes a detailed simulation of tropospheric ozone-NOx-hydrocarbon chemistry as well as aerosols and aerosol precursors. Predicted aerosol species include sulfate, nitrate, ammonium, black carbon, primary organic carbon, and secondary ...
متن کاملAssessment of the global impact of aerosols on tropospheric oxidants
[1] We present here a fully coupled global aerosol and chemistry model for the troposphere. The model is used to assess the interactions between aerosols and chemical oxidants in the troposphere, including (1) the conversion from gas-phase oxidants into the condensed phase during the formation of aerosols, (2) the heterogeneous reactions occurring on the surface of aerosols, and (3) the effect ...
متن کاملTropospheric Aerosol Impacts on Trace-Gas Budgets through Photolysis
Aerosols affect the global budgets of O3, OH and CH4 in part through their alteration of photolysis rates and in part through their direct chemistry interactions with gases (a.k.a. “heterogeneous chemistry”). The first effect is evaluated here with a global tropospheric chemistry transport model using recently developed global climatologies of tropospheric aerosols: a satellite-derived aerosol ...
متن کاملInteractive comment on “Impacts of aerosol direct effects on tropospheric ozone through changes in atmospheric dynamics and photolysis rates” by Jia Xing et al
[Comment]: However, the authors have not considered the prominent way aerosols impact tropospheric ozone formation via heterogeneous reactions which leads me to question the conclusions of this study. Several studies have highlighted the role of aerosols in modulating ozone via heterogeneous reactions (eg., Liao and Seinfeld, 2005; Ti et al., 2005; Pozzoli et al., 2008; Xu et al., 2012; Lou et ...
