Detectability of Artificial Ocean Alkalinization and Stratospheric Aerosol Injection in MPI‐ESM [PDF]

Earth's Future, 2020
AbstractTo monitor the success of carbon dioxide removal (CDR) or solar radiation management (SRM) that offset anthropogenic climate change, the forced response to any external forcing is required to be detectable against internal variability. Thus far, only the detectability of SRM has been examined using both a stationary and nonstationary detection ...

Stratospheric Polar Vortex Exerts Different Controls on the Transport of Tropical and Mid‐Latitude Volcanic Aerosols

Geophysical Research Letters
Moderate volcanic eruptions and extreme wildfires in recent two decades have persistently perturbed global stratospheric aerosol loadings. Based on satellite observations and climate model simulations, we find that these events contribute to ∼67% of ...

Stratospheric aerosol formed by intense volcanism–sea interaction during the 2022 Hunga Ha'apai eruption [PDF]

Atmospheric Chemistry and Physics
The Hunga Tonga eruption on 15 January 2022 (HT-22) induced vigorous volcano–sea interaction. Here we study the stratospheric aerosol and water vapor resulting from the eruption using satellite-based instruments: the CALIOP lidar and the Microwave Limb ...

Observation of sulphate aerosols and SO2 from volcanic eruptions using data from the Atmospheric Chemistry Experiment (ACE) [PDF]

, 2011
Infrared spectra measured by the Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE-FTS) on board of the SCISAT satellite were used to analyse the temporal and spatial evolution of volcanic aerosols from the Kasatochi (August 2008 ...

Model simulations of the chemical and aerosol microphysical evolution of the Sarychev Peak 2009 eruption cloud compared to in situ and satellite observations [PDF]

Atmospheric Chemistry and Physics, 2018
Volcanic eruptions impact climate through the injection of sulfur dioxide (SO2), which is oxidized to form sulfuric acid aerosol particles that can enhance the stratospheric aerosol optical depth (SAOD).

Assessing the Impact of Stratospheric Aerosol Injection on US Convective Weather Environments

Earth's Future, 2023
AbstractContinued climate warming, together with the overall evaluation and implementation of a range of climate mitigation and adaptation approaches, has prompted increasing research into proposed solar climate intervention methods, such as stratospheric aerosol injection (SAI).

Climate response to aerosol injection at different stratospheric locations

Atmospheric Science Letters, 2011
The effect of altitude and latitude of sulfate aerosol injection into the stratosphere on climate is studied with Earth system model INMCM. The model includes the general circulation of the atmosphere and oceans as well as a sulfate aerosol component, and is used to determine the most effective injection scenario for reducing changes in temperature and

Efficacy assessment of stratospheric aerosol scrubbing as a counter climate intervention strategy [PDF]

Atmospheric Chemistry and Physics
Stratospheric Aerosol Injection (SAI) has been proposed to counteract global warming. Countering SAI may prove attractive to actors who oppose deployment and methods have been suggested but not tested for efficacy.

Accessible Climate and Impact Model Output for Studying the Human and Environmental Impacts of Nuclear Conflict

Geoscience Data Journal, Volume 13, Issue 3, July 2026.
When a nuclear weapon is detonated in a region with sufficient fuel loading, the resulting firestorm can lift soot into the stratosphere, where it disperses globally over a few weeks. The soot, or black carbon, blocks sunlight, decreasing temperature and precipitation and depleting ozone.
