Abstract
The U.S. Central UV Calibration Facility (CUCF) at the National Oceanic and Atmospheric Administration (NOAA) of the Earth Systems Laboratory calibrates Yankee Environmental System (YES) UVB-1 broadband radiometers for the USDA UV Monitoring Program. The CUCF has three reference YES UVB-1 broadband radiometers that operate in the field at the CUCF's Table Mountain Test Facility (TMTF). These three reference broadband radiometers are run simultaneously against a reference U111 Spectroradiometer developed by Atmospheric Science Research Center (ASRC) at SUNY. The temporal stability will be shown of the erythema calibration factors of the CUCF reference YES UVB-1 radiometers under clear skies from 1994 until 2005. The USDA UV Monitoring Program has 51 UV broadband radiometers that are characterized and calibrated approximately once every 1-2 years by the CUCF starting in 1997. The average annual changes in the calibration are given for the 51 USDA YES UVB broadband radiometers.
