SGLI  

DÉFINITION

  • The Second generation GLobal Imager(SGLI) on “SHIKISAI” (GCOM-C) is an optical sensor capable of multi-channel observation at wavelengths from near-UV to thermal infrared wavelengths （380nm to 12µm）. SGLI also has polarimetry and forward / backward observation functions at red and near infrared wavelengths. SGLI obtains global observation data once every 2 or 3 days, with resolutions of 250m to 1km. The SGLI observations will improve our understanding of climate change mechanisms through long-term monitoring of aerosols and clouds, as well as vegetation and temperatures, in the land and ocean regions. These observations will also contribute to enhancing the prediction accuracy of future environmental changes by improving sub-processes in numerical climate models. SGLI-derived phytoplankton, aerosol, and vegetation activity are also used for mapping fisheries, monitoring the transport of yellow dust, and monitoring crop growth and estimating crop yield.
