Engineering model testing for SGLI IRS especially TIR radiometric data

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 project is in the last phase of Engineering Model (EM) test to verify the overall sensor system performances. This paper presents outline of SGLI and EM test results, especially about IRS.
