Introducing a Comprehensive Set of Stratospheric Aerosol Injection Strategies

, 2023
Abstract. Stratospheric aerosol injection (SAI) comes with a wide range of possible design choices, such as the location and timing of the injection. Different injection strategies can yield different climate responses; therefore, making informed future decisions on SAI requires an understanding of the range of possible climate outcomes.

The choice of baseline period influences the assessments of the outcomes of Stratospheric Aerosol Injection

Earth's Future, 2023
Abstract The specifics of the simulated injection choices in the case of stratospheric aerosol injections (SAI) are part of the crucial context necessary for meaningfully discussing the impacts that a deployment of SAI would have on the planet.

Microphysical Interactions Determine the Effectiveness of Solar Radiation Modification via Stratospheric Solid Particle Injection

Geophysical Research Letters
Recent studies have suggested that stratospheric aerosol injection (SAI) of solid particles for climate intervention could reduce stratospheric warming compared to injection of SO2.

A fully coupled solid-particle microphysics scheme for stratospheric aerosol injections within the aerosol–chemistry–climate model SOCOL-AERv2 [PDF]

Geoscientific Model Development
Recent studies have suggested that injection of solid particles such as alumina and calcite particles for stratospheric aerosol injection (SAI) instead of sulfur-based injections could reduce some of the adverse side effects of SAI such as ozone ...

Heterogeneous reaction of N₂O₅ with airborne TiO₂ particles and its implication for stratospheric particle injection [PDF]

Atmospheric Chemistry and Physics, 2014
Injection of aerosol particles (or their precursors) into the stratosphere to scatter solar radiation back into space has been suggested as a solar-radiation management scheme for the mitigation of global warming.

Deployment Strategy Shapes the Polar Climate Response to Marine Cloud Brightening

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Marine cloud brightening (MCB) is a proposed solar climate intervention strategy that increases marine cloud reflectivity to cool Earth's surface. While previous studies have largely examined its global temperature and precipitation effects, little is known about how MCB deployment strategies influence polar climate and sea ice.

Stratospheric injection of solid particles reduces side effects on circulation and climate compared to SO2 injections

Environmental Research: Climate
Most research of stratospheric aerosol injection (SAI) for solar radiation modification has focused on injection of SO _2 . However, the resulting sulfuric acid aerosols lead to considerable absorption of terrestrial infrared radiation, resulting in ...

Stratospheric Albedo Modification by Aerosol Injection

, 2009
This paper reviews and develops the proposal, widely discussed but not examined in detail, to use stratospheric aerosols to increase the Earth's albedo to Solar radiation in order to control climate change. The potential of this method has been demonstrated by the "natural experiments" of volcanic injection of sulfate aerosols into the stratosphere ...

Reversal of the ITCZ Shift During the Satellite Era

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract A southward shift of the Intertropical Convergence Zone (ITCZ) during the latter half of the 20th century has been primarily attributed to interhemispheric differences in anthropogenic aerosol forcing. However, in recent decades anthropogenic aerosol emissions have declined, particularly over Northern Hemisphere (NH).
