Observation of polar stratospheric clouds over McMurdo (77.85°S, 166.67°E) (2006-2010)
Polar stratospheric clouds (PSCs) have been observed in the Antarctic winter from 2006 to 2010 at the Antarctic base of McMurdo Station using a newly developed Rayleigh lidar. Total backscatter ratio and volume depolarization at 532 nm have been measured from 9 km up to 30 km with an average of 90 m...
