Abstract

The moon is visible during total lunar eclipses due to sunlight refracted into the earth's shadow by the atmosphere. Stratospheric aerosols can profoundly affect the brightness of the eclipsed moon. Observed brightnesses of 21 lunar eclipses during 1960-1982 are compared with theoretical calculations based on refraction by an aerosol-free atmosphere to yield globally averaged aerosol optical depths. Results indicate the global aerosol loading from the 1982 eruption of El Chichón is similar in magnitude to that from the 1963 Agung eruption.

摘要

在月全食期间，由于阳光被大气折射到地球的阴影中，月球是可见的。平流层气溶胶可以深刻地影响月食时月球的亮度。将 1960 年至 1982 年期间 21 次月食的观测亮度与基于无气溶胶大气折射的理论计算进行了比较，得出了全球平均气溶胶光学厚度。结果表明，1982 年埃尔奇琼火山爆发产生的全球气溶胶负荷与 1963 年阿贡火山爆发产生的负荷相似。
