The Spectrometers for Sky-Scanning, Sun-Tracking Atmospheric Research (4-STAR) is an airborne sun-sky spectrometer that measures direct solar irradiance and sky radiance. These measurements can be used to retrieve column-integrated information on aerosols, clouds, and trace gases such as aerosol optical depth, extinction, and single scattering albedo. 4-STAR operates in the 350-1650 nm wavelength range and has a typical horizontal resolution of about 100 m.
