Other AbstractThe basic characters of the sodium layer density at a low-latitude location (Haikou, China, 20°N, 110°E) are described from analysis of sodium lidar observation data. A Nd:YAG laser pumped dye laser is used to generate the probing beam. The wavelength of the dye laser is set to 589 nm by a sodium fluorescence cell. The energy and divergence of the beam are about 42 mJ and lmrad,respectively. The repetition rate of Nd:YAG laser is 30 Hz. The backscattered fluorescence photons from the sodium layer are collected by a telescope with a 1000 mm diameter primary mirror. A sodium layer density profile of upper atmosphere is derived from lidar files collected during the night of 4 May 2010 in Haikou, China, In this paper, the relative density and the absolute one for the sodium layer profile are studied. This result, shows a good correlation with that reported by Beatty at Arecibo, Puerto Rico (18°N, 67°W). A sporadic sodium layer is observed and lasted 12 minutes.
