AbstractCurrent state of the art for UV solar reference spectroradiometers reaches a total uncertainty of 5% which adversely affects long term analysis of atmospheric changes. A significant contribution to this uncertainty is due to the nonlinearity and quantum efficiency stability of the photomultiplier tubes (PMT) chosen to satisfy the demanding constraints in terms of sensitivity and dynamic range required by solar UV scanning spectroradiometers. A solid state detection system (SSDS) composed by a solid state detector in conjunction with optimized low noise and high sensitive readout electronics is presented as an alternative to PMT to reduce the total uncertainty of QASUME [1]. © 2013 AIP Publishing LLC.
