La photométrie des éclipses de Lune, vue par František Link  : commentaire historique

Abstract

In a 1933 article, Link (1906–1984) shows how to calculate the lunar disc irradiance during a total eclipse, by taking in account the refraction and extinction of light in the Earth’s atmosphere, as well as the limb darkening of the Sun. Hence, he deduces some properties of the terrestrial ozone layer. This article illustrates how Hausdorff’s research on the upper atmosphere, based on the study of refraction and photometry, was extended during the first half of the 20th century, before space research emerged.
