Apollo - US lunar exploration program of satellites with crews of three astronauts. AVHRR - Advanced Very High Resolution Radiometer, a multispectral imaging system carried by the TIROS-NOAA series of meteorological satellites. Band - A wavelength interval in the electromagnetic spectrum. For example, in Landsat images the bands designate specific wavelength intervals at which images are acquired. Beam - A focused pulse of energy Coriolis Force- Force that arises when air moves with respect to the rotating Earth. It causes the wind or water to turn to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.
