1986年南春在南极麦默多站进行了太阳和月亮的可见光谱观测。介绍了观测资料的覆盖范围和观测条件。臭氧的日变化表明，大部分春季臭氧消耗（或南极臭氧“洞”）在9月初迅速发生。在8月和9月期间，极涡内部的总NO2丰度低于约1×1015 cm−2，并且从早晨到黄昏几乎没有日变化。总NO2柱丰度与50毫巴温度密切相关。
Observations of the visible spectra of the sun and moon were obtained at McMurdo Station, Antarctica, during austral spring in 1986. The data coverage and observing conditions are described. Daily variations of ozone suggest that the bulk of the springtime ozone depletion (or the Antarctic ozone “hole”) occurs rapidly during early September. Total NO2 abundances were less than about 1×1015 cm−2 during August and September inside the polar vortex and displayed a near-absence of diurnal variation from morning to evening twilight. The total NO2 column abundance was closely correlated to 50-mbar temperatures.
