Aerosols

An aerosol (abbreviation of "aero-solution") is a suspension of fine solid particles or liquid droplets in air or another gas. Aerosols can be natural or anthropogenic. Examples of natural aerosols are fog, mist, dust, forest exudates and geyser steam. Examples of anthropogenic aerosols are particulate air pollutants and smoke. The liquid or solid particles have diameters typically less than 1 μm; larger particles with a significant settling speed make the mixture a suspension, but the distinction is not clear-cut. In general conversation, aerosol usually refers to an aerosol spray that delivers a consumer product from a can or similar container. …

near-term warming by reducing both CO2 and cooling aerosols (SO2) compared to mitigation strategies targeting emissions of greenhouse gases and black carbon aerosols contribute about 1.8 °C of warming, about 0.7 masked due to the cooling effect of reflective aerosols that are primarily co- emitted along with CO2 21 °C). If we don’t account for these cooling aerosols and only consider gross warming due to greenhouse also reduces the formation of cooling sulfate aerosols by acting as a sink for the hydroxy radical (OH)
