Atmospheric models — Static atmospheric models describe how the ideal gas properties (namely: pressure, temperature, density, and molecular weight) of an atmosphere change, primarily as a function of altitude. For example, the US Standard Atmosphere is essentially a… … Wikipedia
Upper-atmospheric lightning — is an obsolete term that is no longer used by researchers to refer to a family of electrical breakdown phenomena that occurs well above the altitudes of normal lightning. Current usage favors Transient Luminous Event (TLE) to refer to one of the… … Wikipedia
Atmospheric model — A 96 hour forecast of 850 mbar geopotential height and temperature from the Global Forecast System An atmospheric model is a mathematical model constructed around the full set of primitive dynamical equations which govern atmospheric motions. It… … Wikipedia
Atmospheric Neutral Density Experiment — The Atmospheric Neutral Density Experiment (ANDE) is an experiment using two spherical satellites to measure the effects of atmospheric drag on spacecraft. ANDE is part of the Space Test Program of the United States Department of Defense, and was … Wikipedia
Atmospheric reentry — refers to the movement of human made or natural objects as they enter the atmosphere of a planet from outer space, in the case of Earth from an altitude above the edge of space. This article primarily addresses the process of controlled reentry… … Wikipedia
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 field of research and draws on environmental chemistry, physics, meteorology, computer modeling,… … Wikipedia
Atmospheric electricity — is the regular diurnal variations of the Earth s atmospheric electromagnetic network (or, more broadly, any planet s electrical system in its layer of gases). The Earth’s surface, the ionosphere, and the atmosphere is known as the global… … Wikipedia
Atmospheric tide — Atmospheric tides are global scale periodic oscillations of the atmosphere. In many ways they are analogous to ocean tides. Atmospheric tides can be excited by:*The regular day/night cycle in the insolation of the atmosphere *The gravitational… … Wikipedia
Atmospheric dispersion modeling — Industrial air pollution source Atmospheric dispersion modeling is the mathematical simulation of how air pollutants disperse in the ambient atmosphere. It is performed with computer programs that solve the mathematical equations and algorithms… … Wikipedia
Atmospheric Chemistry Observational Databases — Over the last two centuries many atmospheric chemical observations have been made from a variety of ground based, airborne, and orbital platforms and deposited in databases. Many of these databases are publicly available. All of the instruments… … Wikipedia
