A route or reservoir by which a measurable quantity may exit a system, such as by accumulation (in a reservoir) or chemical conversion. Compare source.
Industry:Weather
A satellite designed to demonstrate the feasibility of global ocean monitoring from space. After a successful launch on 28 June 1978, ''Seasat'' produced promising results, but the mission was terminated after only three months following a failure in the satellite's electrical system. Instrumentation flown on ''Seasat'' included a radar altimeter, a microwave scatterometer for measuring surface wind speed and direction, a scanning multichannel microwave radiometer for sea surface temperature, a visible and infrared radiometer, and the first spaceborne synthetic aperture radar.
Industry:Weather
Fragmentation of a molecule into two or more components, which may or may not be charged, as a consequence of absorption of a photon (interaction with electromagnetic radiation).
Industry:Weather
Forecasts based on the governing equations of hydrodynamics. The terminology is typically used to distinguish the forecasts from those based on statistical models.
Industry:Weather
Forecast of hydrologic events on a short-term basis, such as a few hours, up to a few days.
Industry:Weather
Forecast methods based upon analysis of a set and/or series of synoptic charts; the most common means of arriving at a weather forecast. These techniques usually contain elements of a physical, kinematic, and climatological nature and are, to an appreciable degree, subjective. This term is used primarily to distinguish these methods from others such as mesoscale forecasting, numerical forecasting, statistical forecasting, and climatological forecasting.

For U. S. Purposes, the WBAN number used by the National Weather Service to identify a station. For international purposes, the WMO five-digit station designator is used. Compare international index numbers.
Industry:Weather
For radar, the procedure of pointing a radar at the sun to receive and measure the energy radiated by the sun at the radio frequency to which the radar receiver is sensitive. Using the sun as a signal source, it is possible to check the azimuth and elevation alignments of the antenna and to estimate the antenna gain. Antenna gain measurements require knowledge of the solar irradiance in the frequency band of the receiver. This information is available from several observatories around the world that observe the solar spectrum at local noon each day. See solar signal.
