| Definition | A precision radiometer that measures biologically effective solar UV radiation with a spectral response of 280-320nm. Coloured filters and a UV-B phosphor convert incoming UV-B radiation into green light which is then measured by a calibrated solid-state photodetector. The UVB-1 measures global solar UV-B irradiance or the power per unit area of UV-B radiation received by a horizontal surface from the entire hemisphere of the sky. Global radiation includes both light transmitted directly through the atmosphere and light scattered by atmospheric gases and particulate matter in the atmosphere. The UVB-1 measures both the direct and diffuse components of global radiation. Cosine response is ±5% for 0 - 60 degree solar zenith angle and sensitivity is 1.97 volt/(watt/m2) of total UV-B irradiance. |
