摘要: The mesospheric Na layer is generally confined to the region between 80 and 110 km, with a peak near mesopause where density ranges from about 10/sup 3/-10/sup 4/ cm/sup -3/. an excellent tracer of wave motions, lidar studies are now making important contributions gravity waves mesopause. In field astronomy, Ni techniques also being developed for creating artificial guide stars that can be used groundbased adaptive telescopes compensate image distortion caused by atmospheric turbulence. design modern resonance fluorescence lidars described, applications in sciences astronomy discussed. >
