4-STAR
Spectrometers for Sky-Scanning, Sun-Tracking Atmospheric Research

The Spectrometers for Sky-Scanning, Sun-Tracking Atmospheric Research (4-STAR) is a sun-sky spectrometer. It is an airborne instrument that measures direct solar irradiance and sky radiance. The measurements taken can be used to retrieve information on aerosols, clouds, and trace gases.
