Grey scale

Earth science; Remote sensing

A sequence of grey tones ranging from black to white.

X band

Earth science; Remote sensing

Radar wavelength region from 2. 4 to 3. 8 cm.

Thermal IR image

Earth science; Remote sensing

Image acquired by a scanner that records radiation within the thermal IR band.
