Paper Abstract

The design of a newly constructed high performance portable Vis-NIR multiple wavelength sunphotometer is presented. The device measures the incoming flux of direct solar radiation within narrow spectral intervals set by bandpass interference filters. These intervals correspond to the main windows of the visible and near-infrared attenuation spectrum of the atmosphere and to the selected water vapor absorption bands. The instrument's optical features and performance are described. It is explained why the most important parts of the device should be carefully stabilized thermally (detector and amplifier within filters and signal processing unit within to avoid biasing of the solar signal. The overall accuracy of the photometer's output is derived to be better than 0.1% to match requirements in the NIR.
