摘　　要：介绍了一台氮分子（N2）Raman激光雷达系统。利用N2分子Raman散射和气溶胶及分子的Mie—Rayleigh散射信号,通过同时订正分子、气溶胶和臭氧的衰减,反演出对流层中上部大气密度和温度的垂直分布,其结果与常规球载无线电探空仪探测资料对比,在8～18km范围内表现了较好的一致性。其中,二者测量的温度在9～15km高度内相对差别小于4K。N2 molecule vibrational Raman lidar is described in this paper. We obtained air density and temperature distributions in the mid and upper troposphere by simultaneously correcting the attenuation of air molecule, aerosol and ozone. By comparison with the routine radiosonde observations, the distribution trends of air density and temperature obtained by this N2 Raman lidar show a good agreement with ones of radiosonde over the altitudes of 8 km to 18 km. Their relative differences of temperature are smaller than 4 K from 9 km to 15 km altitude.
