中文摘要	The atmospheric density and temperature in lower thermosphere are analyzed using numerical simulation, empirical model, satellite data and ground LIDAR measurement. The WACCM global atmosphere model is used as the numerical simulation method; the empirical models include NRLMSISE-00 and US-76; the satellite data are taken by US SABER/TIMED satellite. The atmospheric density and temperature with an altitude range from 60km to 100km at Germu in August 2013 are measured by a ground LIDAR system. Comparison of the results from different methods shows that the density and temperature are in good agreement below altitudes 90km and 80km, respectively. Above the altitudes, the discrepancy between the different methods increases with increasing altitude. It is also noted that the daily and diurnal variation of density and temperature become significant above 100km altitude.
