Initial results of Rayleigh scattering lidar observations at Zhongshan station, Antarctica
Figures & Tables(5)
Fig. 2. Rayleigh lidar raw signal profile at night on March 6, 2020, at Zhongshan station. The raw data has a vertical bin width of 30 m and an integration time of 1 min
Fig. 3. Comparison of atmospheric density (a) and temperature (c) between lidar (red solid), MSIS model (blue dash), and SABER satellite (green dash) data near Zhongshan station on March 6, 2020. The vertical resolution is 300 m and the temporal resolution is 30 min for lidar data. Lidar measured density uncertainty (b) and temperature uncertainty (d) were also plotted
Fig. 4. Zhongshan station Rayleigh lidar measured temperature (a), density (b), temperature perturbation (c), and density perturbation (d) on June 30, 2020. The density (b) is plotted in color contour under the logarithm scale
