CALIPSO Lidar satellite can make incredibly sharp measurements of the atmosphere, ocean, and ground. Lidar (light detection and ranging) or "laser radar" systems can accurately measure the atmosphere and its chemical construction. Laser systems can detect pollution and other anomalies by using laser spectroscopy. The laser beam stresses molecules that send light quantum in their spectral frequency. Researchers use the same system that determines the elemental construction of the structures by using spectral analysis when they want to determine the star's chemical fingerprint. The same systems can determine any chemical compound in the world. The lidar systems can also search for pollution that is left in oceans and measure earthquakes. The idea is that the altitude of the laser- or lidar satellites can make many missions by using the different types of laser light. When a lidar satellite measures earthquakes that system measures land movements. The high-accurate lida
