| Abstract | “Ozone” is a sensitive topic that arouses interest everywhere. Its presence in the stratosphere affects us all, and its threatened reduction would have such dire consequences that it energizes international campaigns, influences the thinking of governments, and activates substantial alterations in the accustomed habits of millions throughout the world. However, the properties of ozone are not that well known by most people (what is “known” about ozone has generally been relayed through various media channels), while the actual facts concerning its concentration and in particular its reduction require sophisticated scientific measurements that are only accessible to a few and are limited by data that have not always been as plentiful as they are nowadays. This paper describes a new initiative to examine overlooked but potentially informative ozone data from last century's astronomical records. |
