Radiometric Measurements in the UV-B Region of Daylight
The Smithsonian Radiation Biology Laboratory has developed a low level light-monitoring device which can be operated in the natural environment with little maintenance. Such a device has been functioning for over four years at Rockville and for about a year and a half at NASA-Langley in Virginia. The device at Rockville is an original analog version of the integrating digital unit used at Langley. These units are monitoring solar ultraviolet radiation from 280–325 nm in 5 nm bands, using interference filters in pairs. These filters are centered at 285, 290, 300, 305, 310, 315, and 320 nm.
