Here, we show the resulting changes to aerosol and ozone abundances and their radiative forcing using recently updated emission data for the period 1990–2015, as simulated by seven global atmospheric composition models. The models broadly reproduce large-scale changes in surface aerosol and ozone based on observations (e.g. −1 to −3 % yr−1 in aerosols over the USA and Europe). The global mean radiative forcing due to ozone and aerosol changes over the 1990–2015 period increased by +0.17 ± 0.08 W m−2, with approximately one-third due to ozone. This increase is more strongly positive than that reported in IPCC AR5. The main reasons for the increased positive radiative forcing of aerosols over this period are the substantial reduction of global mean SO2 emissions, which is stronger in the new emission inventory compared to that used in the IPCC analysis, and higher black carbon emissions. date: 2017-02-22 date_type: published publisher: Copernicus Publications id_number: 10.5194/acp-17-2709-2017 creators_browse_id: 159 full_text_status: public publication: Atmospheric Chemistry and Physics volume: 17 number: 4 pagerange: 2709-2720 refereed: TRUE issn: 1680-7324 projects: Evaluating the Climate and Air Quality Impacts of Short-Lived Pollutants (ECLIPSE, FP7 282688) coversheets_dirty: FALSE fp7_project: yes fp7_project_id: info:eu-repo/grantAgreement/EC/FP7/282688/EU/Evaluating the Climate and Air Quality Impacts of Short-Lived Pollutants/ECLIPSE fp7_type: info:eu-repo/semantics/article access_rights: info:eu-repo/semantics/openAccess citation: Myhre, G., Aas, W., Cherian, R., Collins, W., Faluvegi, G., Flanner, M., Forster, P., Hodnebrog, Ø., et al.
