  2. Particulates - Wikipedia

    en.wikipedia.org/wiki/Particulates

    In the presence of ammonia, secondary aerosols often take the form of ammonium salts; i.e. ammonium sulfate and ammonium nitrate (both can be dry or in aqueous solution); in the absence of ammonia, secondary compounds take an acidic form as sulfuric acid (liquid aerosol droplets) and nitric acid (atmospheric gas).

  3. CLOUD experiment - Wikipedia

    en.wikipedia.org/wiki/CLOUD_experiment

    CLOUD insofar allows to explain a large fraction of cloud seeds in the lower atmosphere involving sulphuric acid and biogenic aerosols. [10] CLOUD researchers note that cosmic rays have little influence on the formation of sulphuric acid–amine particle formation: "The ion-induced contribution is generally small, reflecting the high stability ...

  4. Cloud - Wikipedia

    en.wikipedia.org/wiki/Cloud

    Clouds have been observed in the atmospheres of other planets and moons in the Solar System and beyond. However, due to their different temperature characteristics, they are often composed of other substances such as methane, ammonia, and sulfuric acid, as well as water. Tropospheric clouds can have a direct effect on climate change on Earth ...

    Sulfuric acid is known to be abundant in the clouds of Venus, in the form of aerosol droplets. In a biochemistry that used sulfuric acid as a solvent, the alkene group (C=C), with two carbon atoms joined by a double bond, could function analogously to the carbonyl group (C=O) in water-based biochemistry. [43]

  6. Aerosol - Wikipedia

    en.wikipedia.org/wiki/Aerosol

    Volcanic aerosol forms in the stratosphere after an eruption as droplets of sulfuric acid that can prevail for up to two years, and reflect sunlight, lowering temperature. Desert dust, mineral particles blown to high altitudes, absorb heat and may be responsible for inhibiting storm cloud formation.

    Microplastics are turning up in unusual places increasingly often as they filter into nearly every facet of life on Earth. They’ve been discovered in drinking water, food, air and even in blood.

  8. 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 .

  9. Volcanic winter - Wikipedia

    en.wikipedia.org/wiki/Volcanic_winter

    The conversion of sulfur dioxide to sulfuric acid, which condenses rapidly in the stratosphere to form fine sulfate aerosols. A volcanic winter is a reduction in global temperatures caused by droplets of sulfuric acid obscuring the Sun and raising Earth's albedo (increasing the reflection of solar radiation) after a large, sulfur-rich, particularly explosive volcanic eruption.
