Seasonal variations of the atmospheric temperature structure at South Pole
Fe/Rayleigh lidar measurements are combined with the high-altitude balloonsonde data and used to characterize the seasonal variations of atmospheric temperature at South Pole from the surface (2.835 km) to 110 km altitude. Twelve-month oscillations, associated with solar UV absorption by ozone, domi...
