Abstract
The Second-generation Global Imager (SGLI) on the Global Change Observation Mission (GCOM) is a multi-band optical imaging radiometer in the wavelength range from near-UV to thermal infrared. SGLI will provide high accuracy measurements of Ocean, Atmosphere, Land and Cryosphere. SGLI consists of two radiometers, the Visible and Near Infrared Radiometer (VNR) and the Infrared Scanning Radiometer (IRS). This paper describes VNR Engineering Model (EM) and Proto Flight Model (PFM) optical test results. Especially we achieved measurement accuracy of ±4% for polarization rate and that of ±1.3deg for polarization direction that enables objective accuracy of aerosol observation.
