Abstract: Characteristics of an instrument for measuring solar ultraviolet-B irradiance are presented together with a description of the instrument. The instrument measures direct and scattered broadband ultraviolet irradiance ...

Abstract: Three approaches to the design of total (global) solar pyranometers that employ new technologies and materials of manufacture are described. The pyranometers are designed to meet or exceed the requirements for high quality ...

Abstract: The U.S. Department of Agriculture's Ultraviolet (UV) Radiation Monitoring Program has been measuring UV radiation since 1994. The initial network of 12 stations employed broadband meters to measure UVB irradiance and ...
