| Zusammenfassung |
Routine measurements of global and diffuse UV irradiances at Briançon
station (1310 m a.s.l.) are used to retrieve the direct solar irradiance and the
aerosol optical depth (AOD), for cloudless days. Data of three years (2003,
2004, 2005) are analyzed; the results confirm those of a preliminary
analysis for 2001, 2002.
The atmosphere is very clear in winter, with AODs between 0.05 and 0.1. The
turbidity increases slowly in spring, starting end of February, with AODs
around 0.2–0.3 in mid summer, some values reaching 0.4. A similar behaviour
is observed for all years, with somewhat higher values in late summer for
the year 2003. |
