摘要利用两枚Sidewinder-H. V. Arcas火箭测量了太阳质子事件发生初期和末期的臭氧分布。这些测量是通过太阳吸收光谱技术获得的，覆盖的高度范围为51-80公里。1969年11月4日的臭氧分布明显低于典型的中纬度数据，但一般处于其他高纬度观测的范围内。目前的光化学传输模型被发现高估臭氧，但在较高的海拔高度与数据的协议。在1969年11月2日扰动的初始阶段，发现臭氧浓度在所有高度上都显着降低。54公里处的变化系数为2，60公里处为3，67公里处为4。臭氧的显著减少被认为是由于颗粒沉淀。
Abstract Two Sidewinder—H.V. Arcas rockets were instrumented to measure the ozone distribution during the initial and final phases of a solar proton event. The measurements were obtained by the technique of solar absorption spectroscopy and covered the altitude range 51–80 km. The ozone distribution of 4 November 1969 is significantly less than typical mid-latitude data, but lies generally within the range of other high-latitude observations. Current photochemical-transport models are found to overestimate ozone but approach agreement with the data at higher altitudes. During the initial phase of the disturbance on 2 November 1969 the ozone concentration is found to be significantly less at all altitudes. The change amounts to a factor of 2 at 54 km, 3 at 60 km, and 4 at 67 km. The pronounced decrease in ozone is believed to result from the particle precipitation.
