China building powerful laser radar to research the atmosphere

The video discusses a new radar facility designed to help researchers study atmospheric particles that protect against cosmic rays and solar winds. Expected to be operational within four years, the facility will feature a laser radar with a range of 1000 kilometers, significantly surpassing the typical 100-kilometer range of atmospheric lasers. The radar will emit a high-energy laser beam capable of penetrating clouds and reaching the edge of the Earth's atmosphere, where it will interact with atmospheric particles. Large optical telescopes will then analyze the faint signals reflected by these particles.
