Wien's displacement law

Earth science; Remote sensing

Describes the shift of the radiant power peak to shorter wavelengths as temperature increases.

scanner

Earth science; Remote sensing

An imaging system in which the IFOV of one or more detectors is swept across the terrain.

kinetic temperature

Earth science; Remote sensing

Internal temperature of an object determined by random molecular motion. Kinetic temperature is measured with a contact thermometer.

probability density function (PDF)

Earth science; Remote sensing

A function indicating the relative frequency with which any measurement may be expected to occur. In remote sensing it is represented by the histogram of DN in one band for a ...

photographic IR

Earth science; Remote sensing

Short-wavelength portion (0. 7 to 0. 9 m) of the IR band that is detectable by IR color film or IR black-and-white film.

geostationary orbit

Earth science; Remote sensing

An orbit at 41 000 km in the direction of the Earth's rotation, which matches speed so that a satellite remains over a fixed point on the Earth's surface.
