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 ...

Interactive stratospheric aerosol models' response to different amounts and altitudes of SO₂ injection during the 1991 Pinatubo eruption [PDF]

Atmospheric Chemistry and Physics, 2023
A previous model intercomparison of the Tambora aerosol cloud has highlighted substantial differences among simulated volcanic aerosol properties in the pre-industrial stratosphere and has led to questions about the applicability of global aerosol models

Climate response to off-equatorial stratospheric sulfur injections in three Earth system models – Part 1: Experimental protocols and surface changes [PDF]

Atmospheric Chemistry and Physics, 2023
There is now substantial literature on climate model studies of equatorial or tropical stratospheric SO2 injections that aim to counteract the surface warming produced by rising concentrations of greenhouse gases.

Stratospheric residence time and the lifetime of volcanic stratospheric aerosols [PDF]

Atmospheric Chemistry and Physics
The amount of time that volcanic aerosols spend in the stratosphere is one of the primary factors influencing the climate impact of volcanic eruptions.

Changing transport processes in the stratosphere by radiative heating of sulfate aerosols [PDF]

Atmospheric Chemistry and Physics, 2017
The injection of sulfur dioxide (SO2) into the stratosphere to form an artificial stratospheric aerosol layer is discussed as an option for solar radiation management.

Short- and long-term stratospheric impact of smoke from the 2019–2020 Australian wildfires [PDF]

Atmospheric Chemistry and Physics, 2023
At the end of December 2019 and beginning of 2020, massive firestorms in Australia formed pyrocumulonimbus clouds (pyroCbs) that acted like enormous smokestacks, pumping smoke to the upper troposphere and stratosphere.

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 ...

Assessing the stratospheric temperature response to volcanic sulfate injections by Mt. Pinatubo: insights from the Interactive Stratospheric Aerosol Model Intercomparison Project [PDF]

Atmospheric Chemistry and Physics
Some major volcanic eruptions, such as the one of Mt. Pinatubo in 1991, can inject large amounts of sulfur dioxide (SO2) into the stratosphere, leading to a volcanic aerosol cloud. This dense aerosol cloud induces a radiative heating of the stratosphere,
