Climatology Of Thin Cirrus Clouds at Gadanki (13.5°N, 79.2°E) Using Ground Based Lidar And Satellite Based Measurements

摘要: High altitude cirrus clouds play a significant role in the radiative balance of Earth atmosphere system. Information on occurrences and their optical properties is essential for climate modeling studies. The influence high thin cirru s important due to thermodynamic properties. In order quantify effect atmosphere, vertical structure these are be characterized. Lidar technique has become unique tool detecting characterizing Ground based LIDAR system offers an excellent way obtain characteristic values formations, although microphysical can also obtained global scale by observations from Earth-orbiting Satellites .The ground-based lidar could provide more intensive measurements continuous basis, compared satellite observations. Utilising both, statistical characteristics, physical retrieved precisely. present study ground using pulsed monostatic at National Atmospheric Research Laboratory [NARL], Gadanki (13.5 0 N, 79.2 E), Andhra Pradesh, India. data range 8-20 km used this study.
