Ozone profiles over McMurdo Station, Antarctica, during August, September, and October of 1986 - 1991
Vertical profiles of ozone and temperature have been measured at McMurdo Station, Antarctica, during the springs of 1986 to 1991, roughly every two days from 25 August to 31 October. Comparisons of temporal histories and average vertical structure for these years reveals some striking consistency in...
