Lidar studies of the nighttime sodium layer over Hefei,China

CHEN Ting-di,XUE Xiang-hui,DOU Xian-kang(School of Earth and Space Sciences,University of Science and Technology of China,Hefei 230026,China)  
In Dec.2005,a Mie-Rayleigh-Sodium fluorescence lidar system was construct at USTC,Hefei,China(31.87°N,117.23°E) for measurements at altitudes between ground level and 110 km,i.e.,aerosol extinction(ground level to 30 km),atmospheric(25~70 km) temperatures,and sodium(80~110 km) density.In the past one year after the lidar was set up,routine observations of sodium layer over Hefei were carried on.The characteristics of the shape,nocturnal variations and seasonal variations of sodium layer were obtained.The results show that sodium abundance reaches maximum value 6.014×109 cm-2 in December,approximately 5 times larger than the June minimum value 1.126×109 cm-2.The abundance shows rather broader minimum values throughout the summer months,the centroid height has no evident seasonal variations,but the RMS width exhibits semi-annual variations.
