| Abstract: | 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. |
