Historically Black Colleges and Universities Solar Radiation Monitoring Network
Funded by the U.S. Department of Energy, the six-station Historically Black Colleges and Universities (HBCU) Solar Radiation Monitoring Network provided five-minute averaged measurements of global and diffuse horizontal solar irradiance from November 1985 through December 1996.
These data were processed at NREL to improve the assessment of the solar radiation resources in the southeastern United States. Three of the stations also measured the direct-normal solar irradiance with a pyrheliometer mounted in an automatic sun tracker. All data are archived in the Standard Broadband Format with quality-assessment indicators. Monthly data summaries and plots are also available for each month.
In January 1997, the HBCU sites became part of the CONFRRM solar monitoring network.
