Nitrate aerosols today and in 2030

Nitrate aerosols today and in 2030: a global simulation including aerosols and tropospheric ozone

Nitrate aerosols are expected to become more important in the future atmosphere due to the expected increase in nitrate precursor emissions and the decline of ammoniumsulphate aerosols in wide regions of this planet. The GISS climate model is used in this study, including atmospheric gasand aerosol phase chemistry to investigate current and future (2030, following the SRES A1B emission scenario...

Nitrate aerosols today and in 2030: importance relative to other aerosol species and tropospheric ozone

Global modeling of nitrate and ammonium: Interaction of aerosols and tropospheric chemistry

[1] Global radiative forcing of nitrate and ammonium aerosols has mostly been estimated from aerosol concentrations calculated at thermodynamic equilibrium or using approximate treatments for their uptake by aerosols. In this study, a more accurate hybrid dynamical approach (HDYN) was used to simulate the uptake of nitrate and ammonium by aerosols and the interaction with tropospheric reactive ...

Aerosol forcing in the Climate Model Intercomparison Project (CMIP5) simulations by HadGEM2ES and the role of ammonium nitrate

[1] The latest Hadley Centre climate model, HadGEM2‐ES, includes Earth system components such as interactive chemistry and eight species of tropospheric aerosols. It has been run for the period 1860–2100 in support of the fifth phase of the Climate Model Intercomparison Project (CMIP5). Anthropogenic aerosol emissions peak between 1980 and 2020, resulting in a present‐day all‐sky top of the atm...

Present and potential future contributions of sulfate, black and organic carbon aerosols from China to global air quality, premature mortality and radiative forcing

Aerosols are harmful to human health and have both direct and indirect effects on climate. China is a major contributor to global emissions of sulfur dioxide (SO2), a sulfate (SO4 2 ) precursor, organic carbon (OC), and black carbon (BC) aerosols. Although increasingly examined, the effect of present and potential future levels of these emissions on global premature mortality and climate change...
