Autor: Sandro Vattioni, Beiping Luo, Aryeh Feinberg, Andrea Stenke, Christof Vockenhuber, Rahel Weber, John A. Dykema, Ulrich K. Krieger, Markus Ammann, Frank Keutsch, Thomas Peter, Gabriel Chiodo

Publikováno v: Geophysical Research Letters, Vol 50, Iss 24, Pp n/a-n/a (2023)

Abstract Compared to stratospheric SO2 injection for climate intervention, alumina particle injection could reduce stratospheric warming and associated adverse impacts. However, heterogeneous chemistry on alumina particles, especially chlorine activa

On August 27, 2013, during the Studies of Emissions and Atmospheric Composition, Clouds and Climate Coupling by Regional Surveys (SEAC4RS) field mission, NASA's ER-2 research aircraft encountered a region of enhanced water vapor, extending over a dep

Stratospheric solar geoengineering without ozone loss

Autor: Debra K. Weisenstein, Frank N. Keutsch, John A. Dykema, David W. Keith

Publikováno v: Proceedings of the National Academy of Sciences. 113:14910-14914

Injecting sulfate aerosol into the stratosphere, the most frequently analyzed proposal for solar geoengineering, may reduce some climate risks, but it would also entail new risks, including ozone loss and heating of the lower tropical stratosphere, w

Improved aerosol radiative properties as a foundation for solar geoengineering risk assessment

Autor: David W. Keith, Frank N. Keutsch, John A. Dykema

Publikováno v: Geophysical Research Letters. 43:7758-7766

Side effects resulting from the deliberate injection of sulfate aerosols intended to partially offset climate change have motivated the investigation of alternatives, including solid aerosol materials. Sulfate aerosols warm the tropical tropopause la

Solar geoengineering using solid aerosol in the stratosphere

Autor: John A. Dykema, David W. Keith, Debra K. Weisenstein

Publikováno v: Atmospheric Chemistry and Physics, Vol 15, Iss 20, Pp 11835-11859 (2015)

Solid aerosol particles have long been proposed as an alternative to sulfate aerosols for solar geoengineering. Any solid aerosol introduced into the stratosphere would be subject to coagulation with itself, producing fractal aggregates, and with the
