Using digital image processing to characterize the Campbell–Stokes sunshine recorder and to derive high-temporal resolution direct solar irradiance

The Campbell–Stokes sunshine recorder (CSSR) has been one of the most commonly used instruments for measuring sunshine duration (SD) through the burn length of a given CSSR card. Many authors have used SD to obtain information about cloudiness and solar radiation (by using Ångström–Prescott type formulas), but the burn width has not been used systematically. In principle, the burn width increas...

Sunshine on MS

tion, and thought that visual solar radiation might provide protection from developing MS. In 1970, a study from Switzerland (which is on a similar latitude in the northern hemisphere as Tasmania is in the southern hemisphere) [5] showed a higher clinical RR in winter and spring months, and a later study (also from the northern hemisphere) [6] of seasonal fluctuations in Gd-enhancing lesions on...
