Acid Rain Damage (DI01204)
Acid rain damage to building taken during NAME, North American Monsoon Experiment, June 2004. Primary sources of industrial pollution include emissions from power plants, smelters, and refineries, which pour oxides of sulfur and nitrogen, and other gases, into the atmosphere. There they react with moist air to become sulfuric and nitric acids, resulting in the formation of acid rain.

Acid Rain model 1983 (DI01237)
Acid Rain modeling 1983. The Acid Deposition Modeling Project begins, co-sponsored by NCAR and the U.S. Environmental Protection Agency. Over four years, the project uses NCAR supercomputers to analyze acid rain and related environmental threats. Its findings feed into the decade-long National Acid Precipitation Assessment Program which concludes in 1990 that acid rain is a serious but manageable problem.
Acidic fog in Southeast Alaska (DI00405), Photo by Lee Klinger
Acidic fog drifts over the dormant volcanoes of Kruzof Island in southeast Alaska. The pH of this fog was measured at 3.9, which is about as acidic as orange juice. The source of the acidity is thought to be the oxidation of natural hydrocarbon and sulfide gases emitted by regional forest, bog, and marine ecosystems. This photograph was taken at 11:00 p.m. on 1 July 1986.
Adelie penguins (DI02282) Photo by Andrew Watt
Adelie penguins on Torgersen Island near the Palmer Station. This species is common all along the coast of Antarctica. Adelies stand about 18 to 30 inches tall and weigh 8 to 9 pounds. They can be identified by white rings around their eyes, beaks mostly covered by feathers, and longer than usual tails. They hunt krill, fish, and squid.

Aerial showing pollution over Mexico City (DI01474)
Aerial photo taken near Mexico City showing biomass burning and pollution. During the project, dubbed MIRAGE (Megacity Impacts on Regional and Global Environments), scientists investigate the chemical transformation of air pollution as it flows from Mexico City to surrounding regions and the globe as a whole, with an eye toward applying what they learn to megacities around the world.
