They include a wide range of phenomena such as dust, fume, smoke, mist, fog, haze, clouds, and smog. Aerosol delivery: There are two proposals for how to create a stratospheric sulfate aerosol cloud, either through release of a precursor gas (SO 2) or the direct release of sulfuric acid (H 2 SO 4) and these face different challenges.

In astronomical terms, albedo is the percentage of sunlight that an object bounces back into space. For example, Sedlacek explains, aerosols can form naturally when pine trees release a chemical called alpha-pinene, an oil that condenses into particles that can be seen suspended as a haze -- for The term aerosol is a catch-all for many kinds of little bits of stuff that end up suspended in the atmosphere, from the surface of the planet all the way to the edges of space. They can be solid Definition of aerosol. 1 : a suspension of fine solid or liquid particles in gas Smoke, fog, and mist are aerosols.
