Airshed. An airshed is a geographical area where local topography and meteorology limit the dispersion of pollutants away from the area. They are formed by air masses moving across a landscape, thus influencing the atmospheric composition of that area. Their boundaries are loosely defined, but can be quantified.
Outline of air pollution dispersion. The following outline is provided as an overview of and topical guide to air pollution dispersion: In environmental science, air pollution dispersion is the distribution of air pollution into the atmosphere. Air pollution is the introduction of particulates, biological molecules, or other harmful materials ...
Assimilative capacity is the ability for pollutants to be absorbed by an environment without detrimental effects to the environment or those who use of it. [1] Natural absorption into an environment is achieved through dilution, dispersion and removal through chemical or biological processes. [1] The term assimilative capacity has been used ...
The California Air Resources Board (CARB or ARB) is an agency of the government of California that aims to reduce air pollution.Established in 1967 when then-governor Ronald Reagan signed the Mulford-Carrell Act, combining the Bureau of Air Sanitation and the Motor Vehicle Pollution Control Board, CARB is a department within the cabinet-level California Environmental Protection Agency.
Thrust is a reaction force described quantitatively by Newton's third law. When a system expels or accelerates mass in one direction, the accelerated mass will cause a force of equal magnitude but opposite direction to be applied to that system. [2] The force applied on a surface in a direction perpendicular or normal to the surface is also ...
Idealized greenhouse model. A schematic representation of a planet's radiation balance with its parent star and the rest of space. Thermal radiation absorbed and emitted by the idealized atmosphere can raise the equilibrium surface temperature. The temperatures of a planet's surface and atmosphere are governed by a delicate balancing of their ...
The Wingfoot Lake Airship Hangar in Suffield, Ohio was constructed in 1917 by the Goodyear Tire and Rubber Company for the production of non-rigid airships and training. Hangar No 1 at Lakehurst Naval Airship Station was built in 1921 to house the Navy's future rigid airships. Additional hangars, which housed the USS Akron (ZRS-4) and USS Macon ...
This is sometimes referred to as a unit of standard atmospheres (atm). Total atmospheric mass is 5.1480×10 18 kg (1.135×10 19 lb), [41] about 2.5% less than would be inferred from the average sea level pressure and Earth's area of 51007.2 megahectares, this portion being displaced by Earth's mountainous terrain.
