Web8 Jan 2024 · 1 Introduction. Deliberate injection of sulfate aerosols in the stratosphere is one of the proposed methods to counter the carbon dioxide (CO 2)-induced warming of the climate.In this method, a part of solar radiation reaching the surface is back-scattered by injecting aerosols or their gaseous precursors into the stratosphere, thus resulting in … WebWhile in the stratosphere, volcanic sulfate aerosol actually absorbs longwave radiation emitted by Earth’s surface, and absorption in the stratosphere tends to result in a cooling of the troposphere below. This vertical pattern of temperature change in the atmosphere influences the behaviour of winds in the lower atmosphere, primarily in winter.
