Seasonal Injection Strategies for Stratospheric Aerosol Geoengineering [PDF]
Geophysical Research Letters, 2019 AbstractSimulations of stratospheric aerosol geoengineering have typically considered injections at a constant rate over the entire year. However, the seasonal variability of both sunlight and the stratospheric circulation suggests seasonally dependent injection strategies.

Stratospheric heating by potential geoengineering aerosols [PDF]
Geophysical Research Letters, 2011 A fixed dynamical heating model is used to investigate the pattern of zonal-mean stratospheric temperature change resulting from geoengineering with aerosols composed of sulfate, titania, limestone and soot.

Timescale for Detecting the Climate Response to Stratospheric Aerosol Geoengineering [PDF]
Journal of Geophysical Research D: Atmospheres, 2019 AbstractStratospheric aerosol geoengineering could be used to maintain global mean temperature despite increased atmospheric greenhouse gas (GHG) concentrations, for example, to meet a 1.5 or 2 °C target. While this might reduce many climate change impacts, the resulting climate would not be the same as one with the same global mean temperature due to ...

Geophysical Research Letters, 2014 AbstractThis paper examines the impact of geoengineering via stratospheric sulfate aerosol on the quasi‐biennial oscillation (QBO) using the NASA Goddard Earth Observing System version 5 Chemistry Climate Model. We performed four 30 year simulations with a continuous injection of sulfur dioxide on the equator at 0° longitude.

Sensitivity of stratospheric geoengineering with black carbon to aerosol size and altitude of injection [PDF]
Journal of Geophysical Research, 2012 Simulations of stratospheric geoengineering with black carbon (BC) aerosols using a general circulation model with fixed sea surface temperatures show that the climate effects strongly depend on aerosol size and altitude of injection. 1 Tg BC a−1 injected into the lower stratosphere would cause little surface cooling for large radii but a large amount ...
