Hemispherically symmetric strategies for stratospheric aerosol injection [PDF]

Earth System Dynamics
Stratospheric aerosol injection (SAI) comes with a wide range of possible design choices, such as the location and timing of the injection. Different stratospheric aerosol injection strategies can yield different climate responses; therefore ...

Heterogeneous reaction of ClONO₂ with TiO₂ and SiO₂ aerosol particles: implications for stratospheric particle injection for climate engineering [PDF]

Atmospheric Chemistry and Physics, 2016
Deliberate injection of aerosol particles into the stratosphere is a potential climate engineering scheme. Particles injected into the stratosphere would scatter solar radiation back to space, thereby reducing the temperature at the Earth's surface ...

An interactive stratospheric aerosol model intercomparison of solar geoengineering by stratospheric injection of SO₂ or accumulation-mode sulfuric acid aerosols [PDF]

Atmospheric Chemistry and Physics, 2022
Studies of stratospheric solar geoengineering have tended to focus on modification of the sulfuric acid aerosol layer, and almost all climate model experiments that mechanistically increase the sulfuric acid aerosol burden assume injection of SO2.

Injection strategy – a driver of atmospheric circulation and ozone response to stratospheric aerosol geoengineering [PDF]

Atmospheric Chemistry and Physics, 2023
Despite offsetting global mean surface temperature, various studies demonstrated that stratospheric aerosol injection (SAI) could influence the recovery of stratospheric ozone and have important impacts on stratospheric and tropospheric circulation ...

Emulating inconsistencies in stratospheric aerosol injection

Environmental Research: Climate
Stratospheric aerosol injection (SAI) would involve the addition of sulfate aerosols in the stratosphere to reflect part of the incoming solar radiation, thereby cooling the climate.

Design space exploration for stratospheric aerosol injection

, 2023
159 pages ; With the uncertainties in the implementation of carbon emission reduction, the increase in global mean temperature is likely to exceed the 1.5◦ C target set by the Paris Agreement by the middle of this century. To address this challenge, stratospheric aerosol injection (SAI) is studied here as a possible supplement to emission reduction to ...

Model physics and chemistry causing intermodel disagreement within the VolMIP-Tambora Interactive Stratospheric Aerosol ensemble [PDF]

Atmospheric Chemistry and Physics, 2021
As part of the Model Intercomparison Project on the climatic response to Volcanic forcing (VolMIP), several climate modeling centers performed a coordinated pre-study experiment with interactive stratospheric aerosol models simulating the volcanic ...

Potential for perceived failure of stratospheric aerosol injection deployment. [PDF]

Proc Natl Acad Sci U S A, 2022
As anthropogenic activities warm the Earth, the fundamental solution of reducing greenhouse gas emissions remains elusive. Given this mitigation gap, global warming may lead to intolerable climate changes as adaptive capacity is exceeded. Thus, there is emerging interest in solar radiation modification, which is the process of deliberately increasing ...

Assessing the consequences of including aerosol absorption in potential stratospheric aerosol injection climate intervention strategies [PDF]

Atmospheric Chemistry and Physics, 2022
Abstract. Theoretical stratospheric aerosol intervention (SAI) strategies model the deliberate injection of aerosols or their precursors into the stratosphere, thereby reflecting incident sunlight back to space and counterbalancing a fraction of the warming due to increased concentrations of greenhouse gases.
