  2. Aerosol - Wikipedia

    en.wikipedia.org/wiki/Aerosol

    Mist and fog are aerosols. An aerosol is a suspension of fine solid particles or liquid droplets in air or another gas. [1] Aerosols can be generated from natural or human causes. The term aerosol commonly refers to the mixture of particulates in air, and not to the particulate matter alone. [2] Examples of natural aerosols are fog, mist or dust.

  3. Particulates - Wikipedia

    en.wikipedia.org/wiki/Particulates

    Human-made (anthropogenic) aerosols account for about 10 percent of the total mass of aerosols in the atmosphere as estimated in 2010. The remaining 90 percent comes from natural sources such as volcanoes , dust storms , forest and grassland fires, living vegetation and sea spray , emitting particulates such as volcanic ash, desert dust, soot ...

  4. Stratospheric aerosol injection - Wikipedia

    en.wikipedia.org/wiki/Stratospheric_aerosol...

    The effect of major volcanic eruptions on sulfate aerosol concentrations and chemical reactions in the atmosphere. Major volcanic eruptions have an overwhelming effect on sulfate aerosol concentrations in the years when they occur: eruptions ranking 4 or greater on the Volcanic Explosivity Index inject SO 2 and water vapor directly into the stratosphere, where they react to create sulfate ...

  5. Atmosphere of Earth - Wikipedia

    en.wikipedia.org/wiki/Atmosphere_of_Earth

    The atmosphere of Earth is composed of a layer of gas mixture that surrounds the Earth's planetary surface (both lands and oceans), known collectively as air, with variable quantities of suspended aerosols and particulates (which create weather features such as clouds and hazes), all retained by Earth's gravity.

  6. Cloud physics - Wikipedia

    en.wikipedia.org/wiki/Cloud_physics

    Cloud physics is the study of the physical processes that lead to the formation, growth and precipitation of atmospheric clouds. These aerosols are found in the troposphere, stratosphere, and mesosphere, which collectively make up the greatest part of the homosphere.

  7. Cloud condensation nuclei - Wikipedia

    en.wikipedia.org/wiki/Cloud_condensation_nuclei

    CCNs are a unique subset of aerosols in the atmosphere on which water vapour condenses. This can affect the radiative properties of clouds and the overall atmosphere. [2] Water vapour requires a non-gaseous surface to make the transition to a liquid; this process is called condensation.

  8. Particulate pollution - Wikipedia

    en.wikipedia.org/wiki/Particulate_pollution

    Because salt spray over the oceans is the overwhelmingly most common form of particulate in the atmosphere, anthropogenic aerosols—those made by human activities—currently account for about 10 percent of the total mass of aerosols in our atmosphere. [11]

  9. Sea spray - Wikipedia

    en.wikipedia.org/wiki/Sea_spray

    Sea spray generated by breaking surface waves. Sea spray consists of aerosol particles formed from the ocean, primarily by ejection into Earth's atmosphere through bursting bubbles at the air-sea interface [1] Sea spray contains both organic matter and inorganic salts that form sea salt aerosol (SSA).
