BORCAL

Domain	Definition
Solar	(B roadband Outdoor Radiometer CALibration) A method of calibrating pyrheliometers and pyranometers based on the summation technique at the Solar Radiation Research Laboratory (SRRL). Up to three days of clear-sky solar irradiance measurements taken at 30-second intervals from sunrise to sunset are used to compute the individual radiometer responsivities. For pyrheliometer calibrations, the reference direct normal irradiance is measured with an electrically self-calibrating absolute cavity radiometer traceable to the World Radiometric Reference (WRR). The individual pyrheliometer responsivity is computed as the mean ratio of the signal from the pyrheliometer (microvolts DC) to the reference irradiance (Watts per square meter) for each of the 30-second data samples. Pyranometer responsivities are computed from the ratio of the signal from each pyranometer (microvolts DC) to the reference global horizontal irradiance determined by the direct normal irradiance (measured with an absolute cavity radiometer) and the simultaneous diffuse horizontal irradiance (measured by a reference pyranometer placed under a solar-tracking shading disk): Global Horizontal = Direct Normal x cos(Z) + Diffuse Horizontal where Z = Solar Zenith Angle at the time of measurement. The reference pyranometer is calibrated prior to use in a BORCAL event by means of the Shade Calibration Technique. (references)
