A complex chemical and atmospheric phenomenon that occurs when emissions of sulfur and nitrogen compounds and other substances are transformed by chemical processes in the atmosphere and then deposited on earth in either wet or dry form. The wet forms, popularly called acid rain, can fall to earth as rain, snow, or fog. The dry forms are acidic gas [..]

Atmospheric deposition of acids in solid or liquid form on the Earth's surface. Also see acid precipitation

The accumulation of an acidic chemical from the atmosphere to the surface of the earth, or to plants and structures at the surface. Acids have high concentrations of hydrogen ions when dissolved in wa [..]

water that falls to or condenses on the Earth's surface as rain, drizzle, snow, sleet, hail, dew, frost, or fog with a pH of less than 5.6

Acid deposition, commonly known as acid rain, occurs when emissions from the combustion of fossil fuels and other industrial processes undergo complex chemical reactions in the atmosphere and fall to [..]

is a comprehensive term for the various ways acidic compounds precipitate from the atmosphere and deposit onto surfaces. It can include: wet deposition by means of acid rain, fog, and snow; and dry de [..]

Deposition that is acidic.

A comprehensive term for the various ways acidic compounds precipitate from the atmosphere and deposit onto surfaces. It can include: 1) wet deposition by means of acid rain, fog and snow; and, 2) dry [..]

Total atmospheric deposition of acidity is determined using both wet and dry deposition measurements. Wet deposition is the portion dissolved in cloud droplets and is deposited during rain or other fo [..]

Acid deposition is the end product of reactions between sulphur oxides (SOx), nitrogen oxides (NOx) and water in the atmosphere. Acid deposition reaches the earth as precipitation (wet deposition: aci [..]

a term for the conversion of sulfur oxide and nitrogen oxide emissions into acidic compounds which precipitate in rain, snow, fog, or dry particles

Acidic air pollution that falls to the ground as either particles (dry deposition), or solutions in rain (wet deposition). The latter is commonly known as "acid rain". Produced from [..]

Atmospheric input to ecosystems of pollutants which may acidify soils and freshwaters; this includes species derived from SO2
