Large Particle Size and Thick Coating Influence Pyrocumulonimbus Smoke Radiative Forcing and Stratospheric Warming: Insights From the 2019–2020 Australian Megafires

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Large particle size and thick coatings have been detected in pyrocumulonimbus (pyroCb) smoke injected into the lower stratosphere, enhancing both extinction and absorption of smoke. Here, we quantified how particle size and coating, via internal mixing of non‐absorbing species on black carbon, influence pyroCb smoke radiative forcing and ...

Northern Hemisphere Wintertime Stratospheric Circulation Response to Smoke Injection From a Regional Nuclear Conflict

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Tropical stratospheric aerosol injections are known to strengthen the wintertime Stratospheric Polar Vortex (SPV). Here, we revisit the circulation response to aerosol perturbations during the first month following injection using chemistry‐climate model simulations of regional nuclear war scenarios.

Assessing GFDL‐ESM4.1 Climate Responses to a Stratospheric Aerosol Injection Strategy Intended to Avoid Overshoot 2.0°C Warming

Geophysical Research Letters
In this work, we apply the GFDL Earth System Model (GFDL‐ESM4.1) to explore the climate responses to a stratospheric aerosol injection (SAI) scenario that aims to restrict global warming to 2.0°C above pre‐industrial levels (1850–1900) under the CMIP6 ...

Stratospheric Smoke With Unprecedentedly High Backscatter Observed by Lidars Above Southern France

Geophysical Research Letters, 2018
Extreme pyroconvection events triggered by wildfires in northwest Canada and United States during August 2017 resulted in vast injection of combustion products into the stratosphere.

Using optimization tools to explore stratospheric aerosol injection strategies

Earth System Dynamics
Abstract. Stratospheric aerosol injection (SAI), as a possible supplement to emission reduction, has the potential to reduce some of the impacts associated with climate change. However, the outcomes will depend on how it is deployed: not just how much but also the latitudes of injection and the distribution of injection rates across those latitudes ...

Impacts of hemispheric solar geoengineering on tropical cyclone frequency

Nature Communications, 2017
Solar geoengineering has been proposed as a means of mitigating the warming effects of climate change, yet the consequences of such action remain uncertain. Here, using a general circulation model, the authors evaluate the effect of stratospheric aerosol
