SGLI product processing flow
A
The GCOM-C/SGLI products are categorized into Levels 1 to 3, depending on the processing applied.
Level 1 (L1) processing: Performs radiometric and geometric corrections, and generates radiance data used as input for higher-level processing.
Level 2 (L2) processing: Uses L1B or other L2 products as input to derive various physical parameters.
Level 3 (L3) processing: Uses L2 products as input to produce global time-series statistics.
A simplified diagram of the L2 data flow is shown below.
