摘要：
Energetic solar protons are a natural source of ozone depletion due to nitric oxides they produce in the earth's atmosphere. In March 1989, following a period of intense solar activity, the TOMS instrument aboard the Nimbus 7 satellite recorded very similar ozone losses over both polar caps for areas extending from 90-degrees to 70-degrees. Ozone depletions of 7.4 x 10(9) kg for the south polar cap and 8.0 x 10(9) kg for the north polar cap indicate the degree of symmetry over the polar caps.
