Stratospheric sulfate geoengineering could enhance the terrestrial photosynthesis rate [PDF]
Atmospheric Chemistry and Physics, 2016 Stratospheric sulfate geoengineering could impact the terrestrial carbon cycle by enhancing the carbon sink. With an 8 Tg yr−1 injection of SO2 to produce a stratospheric aerosol cloud to balance anthropogenic radiative forcing from the Representative

Solar geoengineering using solid aerosol in the stratosphere [PDF]
Atmospheric Chemistry and Physics, 2015 Solid aerosol particles have long been proposed as an alternative to sulfate aerosols for solar geoengineering. Any solid aerosol introduced into the stratosphere would be subject to coagulation with itself, producing fractal aggregates, and with the ...

Detection of the temperature responses to stratospheric sulphate aerosol geoengineering [PDF]
Stratospheric sulphate aerosol injection has been proposed as a potential way to cool the\ud climate and alleviate some of the adverse impacts of climate change. Both prudent climate\ud policy-making and successful geoengineering monitoring would require robust knowledge\ud of the detectability of the geoengineering effects amid other externally forced

How large is the design space for stratospheric aerosol geoengineering? [PDF]
Earth System Dynamics, 2021 Abstract. Stratospheric aerosol injection (SAI), as a possible supplement to emission reduction, has the potential to reduce some of the risks associated with climate change. Adding aerosols to the lower stratosphere results in global cooling. However, different choices for the aerosol injection latitude(s) and season(s) have been shown to lead to ...

Potential of future stratospheric ozone loss in the midlatitudes under global warming and sulfate geoengineering [PDF]
Atmospheric Chemistry and Physics, 2021 The potential of heterogeneous chlorine activation in the midlatitude lowermost stratosphere during summer is a matter of debate. The occurrence of heterogeneous chlorine activation through the presence of aerosol particles could cause ozone destruction.

An Update on Engineering Issues Concerning Stratospheric Aerosol Injection for Geoengineering [PDF]
Environmental Research Communications, 2020 Abstract Solar Radiation Management (SRM) geoengineering is a proposed response to anthropogenic global warming (AGW). Stratospheric aerosol injection (SAI) is one proposed method, reliant on lofting material into the stratosphere.

Impact of geoengineered aerosols on the troposphere and stratosphere [PDF]
Journal of Geophysical Research: Atmospheres, 2009 A coupled chemistry climate model, the Whole Atmosphere Community Climate Model was used to perform a transient climate simulation to quantify the impact of geoengineered aerosols on atmospheric processes. In contrast to previous model studies, the impact on stratospheric chemistry, including heterogeneous chemistry in the polar regions, is considered ...

Sensitivity of the radiative forcing by stratospheric sulfur geoengineering to the amount and strategy of the SO2injection studied with the LMDZ-S3A model [PDF]
Atmospheric Chemistry and Physics, 2018 The enhancement of the stratospheric sulfate aerosol layer has been proposed as a method of geoengineering to abate global warming. Previous modelling studies found that stratospheric aerosol geoengineering (SAG) could effectively compensate for the ...

AGU Advances, 2023 Studies of the impacts of solar geoengineering have mostly ignored tropospheric chemistry. By decreasing the sunlight reaching Earth's surface, geoengineering may help mitigate anthropogenic climate change, but changing sunlight also alters the rates of ...

Modelling the size distribution of geoengineered stratospheric aerosols [PDF]
Atmospheric Science Letters, 2010 AbstractA modelling study on the growth of geoengineered stratospheric aerosols reveals that in steady state a large fraction of aerosols grow to micrometre sizes so that the sedimentation of aerosols might limit the geoengineered aerosol layer's ability to achieve its target cooling effect.
