Operation concept of the second-generation global imager (SGLI)

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 will provide the global scale multi spectral data with about 2 days frequency. The observation data over the land area is 250m resolution with more than 1000km swath, and the ocean area in 1km resolution. SGLI also has a unique tilting data to realize the directional polarized observation with red and near infrared wavelength. This paper describes the operation concept and current status of the SGLI instrument development.
