We have a new paper out today, looking more in detail at the potential air quality impacts of Stratospheric Aerosol Injections, finding them more driven by climatic feedbacks than by deposition. This is the 1st questions one receives when discussing this, so really important to explore in depth!

Air quality impacts of stratospheric aerosol injections are likely small and mainly driven by changes in climate, not aerosol settling
Abstract. Stratospheric aerosol injection (SAI) is a proposed climate intervention method to offset future global warming through increased solar reflection in the stratosphere, but its broader enviro...
