One of the main layers of the troposphere, it is the layer of transition between the surface boundary layer, where shearing stress is constant, and the free atmosphere, where the atmosphere is treated as an ideal fluid in approximate geostrophic balance. Also called spiral layer. Together with the surface boundary layer, it makes up the planetary boundary layer.

One of the radiation laws that states that the amount of energy radiated per unit time from a unit surface area of an ideal blackbody is proportional to the fourth power of the absolute temperature of the blackbody. This law was established experimentally by Stefan and was given theoretical support by thermodynamic reasoning of Boltzmann. This law may be deduced by integrating Planck's law over the entire frequency spectrum.

One of two days during the year when the declination of the Sun is at the equator. The autumnal equinox denotes the first day of the fall season. For the Northern Hemisphere, the date of autumnal equinox on either September 22 or 23 (changes yearly). March 20 or 21 is the date of the autumnal equinox in the Southern Hemisphere. During the autumnal equinox, all locations on the Earth (except the poles) experience equal (12 hour) day and night.

Operated by NOAA, they are designated "NOAA satellites. " Included in this group are the current series of TIROS-N satellites, the third-generation polar-orbiting environmental spacecraft operated by NOAA.

Part of the Kuroshio system . Between longitudes 155 degrees and 160 degrees, considerable water turns south and southwest forming part of the Kuroshio countercurrent. It runs at a distance of approximately 700 km from the coast as the eastern branch of a large whirl on the right-hand side of the Kuroshio .

Part of the northern branch of the North Atlantic current , which flows northward along the coast of Norway. = The water of the Norwegian current eventually enters the Arctic Ocean, from which the main discharge is via the east Greenland current .
Industry:Earth science
Particles, other than water or ice, suspended in the atmosphere ranging in radius from one-hundredth to one-ten-millionth of a centimeter -- or 102 to 10-3 microns (µ). Aerosols are important as nuclei for the condensation of water droplets and ice crystals, and as participants in various atmospheric chemical reactions. Perhaps most significantly, they absorb solar radiation, then emit and scatter it, influencing the radiation budget of the Earth-atmosphere system, which in turn influences the climate on Earth's surface. Aerosols from volcanic eruptions can lead to a cooling at the surface, which may delay greenhouse warming for a few years following a major eruption.
Industry:Earth science
Period of time when glaciers dominate the landscape of the Earth. The last major Ice Age was during the Pleistocene epoch.
Industry:Earth science
Periods of sea level fall, when areas of submerged seafloor are exposed above sea level by basin-ward migration of a shoreline.
