Ji, Duoying; et al. (2018): Extreme temperature and precipitation response to solar dimming and stratospheric aerosol geoengineering

Ji, Duoying; Fang, Songsong; Curry, Charles L.; Kashimura, Hiroki; Watanabe, Shingo; Cole, Jason N. S. et al. (2018): Extreme temperature and precipitation response to solar dimming and stratospheric aerosol geoengineering. In Atmos. Chem. Phys. Discuss., pp. 1–36. DOI: 10.5194/acp-2018-131.

"We examine extreme temperature and precipitation under two potential geoengineering methods forming part of the Geoengineering Model Intercomparison Project (GeoMIP). The solar dimming experiment G1 is designed to completely offset the global mean radiative forcing due to a CO2-quadrupling experiment (abrupt 4 × CO2), while in GeoMIP experiment G4, the radiative forcing due to the representative concentration pathway 4.5 (RCP4.5) scenario is partly offset by a simulated layer of aerosols in the stratosphere. Both G1 and G4 geoengineering simulations lead to lower maximum temperatures at higher latitudes, and on land primarily through feedback effects involving high latitude processes such as snow cover, sea ice and soil moisture."

Crook, J.; et al. (2015): A Comparison of Temperature and Precipitation Responses to Different Earth Radiation Management Geoengineering Schemes

Crook, J.; Jackson, L. S.; Osprey, S. M.; Forster, P. M. (2015): A Comparison of Temperature and Precipitation Responses to Different Earth Radiation Management Geoengineering Schemes. In J. Geophys. Res. Atmos., pp. n/a-n/a. DOI 10.1002/2015JD023269

"We compare six different radiation management schemes that use surface, troposphere and stratosphere interventions in a single climate model in which we projected future climate from 2020 to 2099 based on RCP4.5. We analyze the surface air temperature responses to determine how effective the schemes are at returning temperature to its 1986-2005 climatology and analyze precipitation responses to compare side effects."
