Remote sensing
Shuttle multispectral infrared radiometer (SMIRR)
Earth science; Remote sensing
A non-imaging spectroradiometer carried by the NASA Space Shuttle covering ten narrow wavebands in the 0. 5-2. 4 m range.
Cross-polarized
Earth science; Remote sensing
Describes a radar pulse in which the polarisation direction of the return is normal to the polarisation direction of the transmission. Cross-polarized images may be HV (horizontal transmit, vertical ...
Skylight
Earth science; Remote sensing
Component of light that is strongly scattered by the atmosphere and consists predominantly of shorter wavelengths.
Previsual symptom
Earth science; Remote sensing
A vegetation anomaly that is recognisable on IR film before it is visible to the naked eye or on normal colour photographs. It results when stressed vegetation loses its ability to reflect ...
Rayleigh criterion
Earth science; Remote sensing
In radar, the relationship between surface roughness, depression angle, and wavelength that determines whether a surface will respond in a rough or smooth fashion to the radar pulse.
Image
Earth science; Remote sensing
Pictorial representation of a scene recorded by a remote sensing system. Although image is a general term, it is commonly restricted to representations acquired by non-photographic methods.
Thermal conductivity (K)
Earth science; Remote sensing
Measure of the rate at which heat will pass through a material, expressed in calories per centimetre per second per degree Centigrade.
