The GCOM-C (Global Change Observation Mission - Carbon cycle)
aims to contribute to surface and atmospheric measurements related to the carbon cycle and
the radiation budget. The payload consists of a second-generation GLI (SGLI) instrument.
SGLI (Second Generation Global Imager). SGLI is an advanced multi-purpose
visible/infrared (VNIR) imager of GLI heritage, flown on ADEOS-II.
The objective is to measure ocean color, land use and vegetation, snow and ice, clouds,
aerosols and water vapor, etc.
- The largest target of SGLI is to retrieve global aerosol distributions. To achieve this
target, SGLI will have 2 polarization channels with 3 directions
- SGLI is mainly focused to land and coastal areas. There are 11 channels with an IFOV of
250 m. GLI on ADEOS-II had only 6 channels of 250 m resolution.
- SGLI is a pushbroom instrument providing 29 channels in the VNIR (Visible Near Infrared)
spectral region. In addition, there are 6 channels in the SWIR (Shortwave Infrared) and
TIR (Thermal Infrared) regions being served by a whiskbroom scanner (mechanical method).
