A signal that consists of several distinguishable components. A multivariate signal may contain information that describes both the temporal and spatial variability of a single physical quantity.
Industry:Weather
An analysis procedure based on derivation of an analytic formula containing two or more variables to approximate values of a physical quantity at specified data points. The resulting formula serves as an interpolating function to estimate the physical quantity between data points. When two independent variables are used, the result is the equation of a surface that allows objective determination of the isopleths. In a typical meteorological application, objective analysis could be used to derive from scattered observations an expression for contour height as a continuous function of latitude and longitude for the purpose of generating a weather map.
Industry:Weather
Sea ice that has survived more than two summer melt seasons. Such ice is typically 3 m or more thick, is less saline, and has smoother hummocks and ridges than does younger ice. Undeformed multiyear ice is distinguished by its undular surface (remnants of drained or refrozen melt ponds). Multiyear ridges are distinct from first-year ridges in that they are typically smaller, more rounded, nearly solid ice and are therefore a serious impediment to surface ships.
Industry:Weather
A remote sensing device that is capable of recording data in several bands of the electromagnetic spectrum.
Industry:Weather
A device to collect a variety of data and then interleave the data into a single record or onto a telecommunications link. The reverse device is a demultiplexor.
Industry:Weather
Remote sensing in two or more spectral bands simultaneously, such as visible and infrared.
Industry:Weather
In pulsed radar, an echo from a given transmitted pulse that is not received until transmission of one or more additional pulses. Such echoes appear on a display at the wrong range because of range folding. See maximum unambiguous range.
Industry:Weather
In a porous medium, the simultaneous flow of at least two immiscible fluids. Compare miscible displacement.
Industry:Weather
A reservoir designed and operated to serve two or more purposes, such as flood control, hydroelectric power, navigation, irrigation, pollution control, water supply, and recreation.
Industry:Weather
Radiative transfer in which more than one scattering event may be of importance before transmission, reflection, or absorption. Multiple-scattering is the dominant effect on the transfer of solar radiation within clouds, giving rise to diffuse radiation. Compare single-scattering.
