The atmosphere is divided into troposphere (approximately 10-20 km from the ground), stratosphere (approximately 20-50 km from the ground), middle layer (approximately 50-85 km from the ground), and thermal layer (approximately 100-800 km from the ground) ) And escape layer. The atmosphere of the hot layer is called the green laser pointer ionosphere because it is exposed to solar radiation, the temperature is high, and gas molecules or atoms are ionized in large quantities and can conduct electricity.
We call these uncharged atmospheres below the thermal layer the neutral atmosphere, and the system detects around the neutral atmosphere. Over the past few decades, atmospheric sounding technology has made great progress in many aspects. The scientific and technological circles have realized the detection of the atmosphere through different cutting-edge green laser pointer technologies, and many important scientific results have been produced accordingly.
The scientific goal of the development system is to obtain the simultaneous variation characteristics of multiple atmospheric elements in the same vertical gas column, so as to realize the study of atmospheric vertical structure, motion changes and component transport. Regarding the system, in general terms, it is to place multiple observation devices at the same station to perform simultaneous observation of the atmosphere in the same area in the direction of the zenith.
