GCOM-C/SGLI Level-2 ocean color products generation

The SGLI instrument, which is to be launched by JAXA in March 2017 aboard GCOM-C satellite, conducts ocean color observation in 250 m spatial resolution (SST in 500 m resolution) over coastal region, in addition to the global ocean observation in 1 km resolution. We first describe here the SGLI Level 2 (L2) ocean standard products, which consist of 6 ocean color parameters and 1 SST parameter, and then briefly describe the product generation data flow together with the algorithms implemented in the production system. The required time and memory size of the Level-2 data generation was evaluated over a simulated SGLI data scene, which indicates that the modules meet the standard L2 data generation system requirements, although further optimization in the processing code will be pursued.
