One atmosphere (1 atm) is defined to be equal to 101,325 pascals a reference or standard pressure is commonly 1 atm a reference or standard pressure is commonly 1 atm in other cases, standard temperature and pressure or stp is used. Atmospheric science, second edition, is the long-awaited update of the classic atmospheric science text, which helped define the field nearly 30 years ago and has served as the cor read full description.
Atmospheric chemistry and physics (acp) is an international scientific journal dedicated to the publication and public discussion of high-quality studies investigating the earth's atmosphere and the underlying chemical and physical processes.
Topics include photochemistry, kinetics, and thermodynamics important to the chemistry of the atmosphere stratospheric ozone depletion oxidation chemistry of the troposphere photochemical smog aerosol chemistry and sources and sinks of greenhouse gases and other climate forcers. Atmospheric scientists typically need a bachelor’s degree, either in atmospheric science or a related scientific field that specifically studies atmospheric qualities and phenomena bachelor’s degrees in physics, chemistry, or geology are usually adequate, alternative preparation for those who wish to enter the atmospheric sciences. Atmospheric chemistry is a branch of atmospheric science in which the chemistry of the earth's atmosphere and that of other planets is studied it is a multidisciplinary approach of research and draws on environmental chemistry , physics , meteorology , computer modeling , oceanography , geology and volcanology and other disciplines.
Atmospheric chemistry studies were originally concerned with determining the major gases in the earth's atmosphere in the latter half of the past century, as air pollution became an increasing problem in many large cities, attention turned to identifying the sources, properties, and effects of the myriad of chemical species that exist in the natural and polluted atmosphere.
A body is more likely to retain an atmosphere over time if gravity is high and the temperature of the atmosphere is low the composition of the earth's atmosphere is about 78 percent nitrogen, 21 percent oxygen, 09 percent argon, with water vapor, carbon dioxide, and other gases. Eurekalert is an online science news service featuring health, medicine, science and technology news from leading research institutions and universities sponsored by aaas, the science society. The earth's atmosphere is showcased in this highly oblique shot of the earth taken from space the atmosphere, composed of 78 percent nitrogen, 21 percent oxygen and 1 percent other constituents, shields us from falling meteors, as well as nearly all harmful radiation coming from the sun and other stars.
