Lamp calibrated UV/Visible irradiance is the irradiance in Watts per (square meter per nanometer) measured by the UV/Visible MFRSR that has been calibrated using a NIST traceable lamp in a laboratory setting. Our lamp calibrated irradiances are from each nominal wavelength of the UV Shadowband(300, 305, 311, 317, 325, 332, 368 nm) and Visible Shadowband(Open, 415, 500, 615, 673, 870, 940 nm). The lamp calibrations were done before 2010. Data is available only 18 months after the last lamp calibration.
The data is downloaded in CSV format. Each set of data has a header. The header lines begin wth the # sign, and contains a description of location and data, along with possible data issues. The nighttime data is set to -9999 and data that are not currently available or associated with instrument errors are set to -9998.
