Engineering Physics Annotation << Back New methods for calibration of pyranometers by utilization of reference photometric channels of measurements Kh.G. Asadov, S.N. Abdullaeva In the article the new methods for calibration of sun pyranometers operating in UV and visible bands of spectrum have been suggested. These methods envisage utilization of additional reference photometric channels. The analytical formulas for calculation of calibration factors and static compensation functions have been proposed. Keywords: Pyranometers, calibration, solar radiation, measurement channels, atmosphere. E-mail: asadzade@rambler.ru
