The American Meteorological Society promotes the development and dissemination of information and education on the atmospheric and related oceanic and hydrologic sciences and the advancement of their professional applications. Founded in 1919, AMS has a membership of more than 14,000 professionals, ...
A graphical or mathematical approximation scheme for determining the propagation of electromagnetic or sound waves by following the path of rays obeying the laws of reflection and refraction. Applications of ray tracing to atmospheric problems include estimating rainbow angles, determining the characteristics of mirages, and mapping the propagation of sound in the atmosphere and oceans.
Industry:Weather
A graph of soil water content as a function of depth in the soil.
Industry:Weather
A graduated scale placed in a position so that the stage of a stream may be read directly therefrom; a type of river gauge. Staff gauges may be painted on bridge piers and pilings, and painted wooden scales or enameled metal scales may be mounted on bridge piers, docks, trees, or specially constructed supports to be partially submerged by the stream at all times.
Industry:Weather
A geological formation where the pore spaces are fully saturated with water, that is, groundwater.
Industry:Weather
A generic term for a device that measures the intensity of radiation as a function of frequency (or wavelength) of the radiation or that breaks down any signal into its frequency components.
Industry:Weather
A general term to include all means of radio signals used for navigation, typically for aircraft, ships, and other transportation systems; for example, the nondirectional Beacon (NDB), long-range navigation (LORAN), tactical air navigation (TACAN), distance measuring equipment (DME), very high frequency omnirange tactical air navigation (VORTAC), the Omega system, and the Global Positioning System (GPS).
Industry:Weather
A generator used for producing cloud seeding particles and injecting them into clouds. The type is selected for the particular seeding material, application, and delivery system. Different types of seeding devices have been used, including combustion burners, pyrotechnic flares, atomizers, dry powder dispersal systems, dry-ice crushers, and dispensers of liquids that cool substantially on evaporation (such as propane or liquid CO<sub>2</sub>).
Industry:Weather
A gaseous component of the atmosphere with its mixing ratio nearly constant with time and height.
Industry:Weather
A general term referring to the radiation reflected from, or scattered back through, a given surface in response to radiation incident on the surface with the same wavelength or wavelength range. Different definitions arise depending on the directionality of the radiation under consideration. Reflectance in terms of the ratio of reflected to incident irradiance is generally termed albedo, which may also be described in terms of the directional-hemispherical reflectance (when the incident irradiance is from a specific direction), or the bihemispherical reflectance (when the incident irradiance is diffuse). Reflectance of radiance from a specified incident direction into a specified reflected direction is termed the bidirectional reflectance, which may also be described by the bidirectional reflection function (BDRF), the bidirectional reflectance distribution function (BRDF), or the bidirectional reflectance factor. See reflectivity.
Industry:Weather
A general term for a dry heiligenschein, moist heiligenschein, or sylvanshine.
