Stratospheric atmospheric injection
Web1 Jun 2024 · Stratospheric aerosols, in particular, have a direct impact on climate by changing Earth's energy balance through scattering or absorbing solar radiation. For example, large volcanic eruptions powerful enough to inject aerosols into the stratosphere (such at Mt. Pinatubo), have been shown to cause global cooling and influence ozone … Web13 Oct 2024 · Stratospheric aerosol injection would involve flying aircraft into the stratosphere, or between 10 miles and 30 miles skyward, and spraying a fine mist that …

WebSo far, Calbuco has released an estimated 0.3 to 0.4 teragrams (0.3 to 0.4 million tons) of SO 2 into the atmosphere. The gas was injected into the stratosphere (as high as 21 kilometers), where it will last much longer and travel much farther than if released closer to the surface. The SO 2 will gradually convert to sulfate aerosol particles. WebSymonds, Rose, Bluth, and Gerlach concluded that stratospheric injection of sulfur dioxide (SO2) is the principal atmospheric and global impact of volcanic eruptions via SO2 + OH + 3H2O -> H2SO4 (l) + HO2 The SO2 converts to sulfuric acid aerosols that block incoming solar radiation and contribute to ozone destruction. The blocked solar radiation can cause …
