SkyDOAS Emission Measurement System

Air Monitoring System from FluxSense

The SkyDOAS (Sky Differential Optical Absorption Spectroscopy) instrument system measures atmospheric emissions (flux) of SO2, NO2 and HCHO using zenith-scattered solar UV-light (SkyDOAS). The system consists of a UV-Spectrometer Unit and a Solar Telescope. The system also includes a control unit, an optical fiber and a…
