Ultraviolet radiation watch in Portugal

Ultraviolet radiation monitoring in Portugal started in the eighties using a broadband type detector installed at Lisbon. Currently, the Portuguese Institute of Meteorology has set up a new ultraviolet network using both spectral and broadband detectors covering most of the mainland territory and Madeira islands. Ultraviolet monitoring is complemented by the ultraviolet Index forecasting program started in 1999. A brief historical view, methodology and some results of the ultraviolet watch in Portugal are shown. (author)
