Lidar Observations of Polar Mesospheric Clouds at South Pole: Diurnal Variations
Polar mesospheric clouds (PMCs) were observed by a ground-based Fe Boltzmann temperature lidar for 65 h on 17-19 and 24-26 January 2000 above the geographic South Pole. The mean PMC backscatter ratio, volume backscatter coetficient, total backscatter coetficient, layer centroid altitude, and layer rms width are 53.5, 2.9x10 -9 m-Xsr -x, 4.3x10 -6 sr -x, 85.37 km, and 0.78 km, respectively. Stro...
متن کاملLidar Observations of Polar Mesospheric Clouds at South Pole: Seasonal Variations
Polar mesospheric clouds (PMCs) were observed above the geographic South Pole by an Fe Boltzmann temperature lidar from 11 Dec 99 to 24 Feb 00. During this 76-day period 297 h of observations were made on 33 different days and PMCs were detected 66.5% of the time. The mean PMC peak backscatter ratio, peak volume backscatter coefficient, total backscatter coefficient, layer centroid altitude, an...
متن کاملLidar studies of interannual, seasonal, and diurnal variations of polar mesospheric clouds at the South Pole
[1] Polar mesospheric clouds (PMC) were observed by an Fe Boltzmann temperature lidar at the South Pole in the 1999–2000 and 2000–2001 austral summer seasons. We report the study of interannual, seasonal, and diurnal variations of PMC using more than 430 h of PMC data. The most significant differences between the two seasons are that in the 2000– 2001 season, the PMC mean total backscatter coef...

متن کاملNear—infrared sky brightness monitor for the South Pole
The antarctic plateau has the potential for being the best site on Earth for conducting astronomical observations from the near-infrared to the sub-millimeter. Particular gains are expected in the 1 to 5 micron region, where the high altitude, low water vapour content, and low thermal emission from the atmosphere combine to create observing conditions unequalled elsewhere on the surface of the ...
