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 ...
Inorganic aerosols are mainly produced when sulfur dioxide reacts with water vapor to form gaseous sulfuric acid and various salts (often through an oxidation reaction in the clouds), which are then thought to experience hygroscopic growth and coagulation and then shrink through evaporation [16] [14] as microscopic liquid droplets or fine ...
Venusian clouds are thick and are composed mainly (75–96%) of sulfuric acid droplets. [51] These clouds obscure the surface of Venus from optical imaging, and reflect about 75% [52] of the sunlight that falls on them. [1] The geometric albedo, a common measure of reflectivity, is the highest of any planet in the Solar System.
Type Ib clouds contain small, spherical particles (non-depolarising), of a liquid supercooled ternary solution (STS) of sulfuric acid, nitric acid, and water. [4] Type Ic clouds consist of metastable water-rich nitric acid in a solid phase. [8] Type II clouds, which are very rarely observed in the Arctic, have cirriform and lenticular sub-types ...
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 ...
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.
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.
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 .
