Product Summary

GCOM-C/SGLI L2 Sea Surface Temperature (1km) dataset is obtained from the SGLI sensor onboard GCOM-C and produced by the Japan Aerospace Exploration Agency (JAXA). GCOM-C is Sun-synchronous sub-recurrent Orbit satellite launched on December 23, 2017, which mounts SGLI and conducts long-term global observations of geophysical variables related to the global climate system across 28 items including aerosol and vegetation over 4 areas of atmosphere, land, ocean, and cryosphere. The data will be used to contribute to higher accuracy of global warming prediction. The SGLI has swath of 1150 km in the visible band and 1400 km in the infrared band. Level 2 products are defined to be products composed of physical quantity data that is calculated based on Level 1B products and meteorological data, as well as various additional data related to the physical quantity data.
This dataset includes Sea Surface Temperature (SST) and Cloud probability (Cloud_probability).
SST data is the temperature of sea surface. The physical quantity unit is degree.
Cloud Probability data is possibly affected by clouds for each SST pixel. The unit is %.
The package includes not only this product but also QA_Flag data with the same spatial resolution as the auxiliary data. The provided format is HDF5. The Spatial resolution is 1 km. The projection method is L1B reference coordinates. The generation unit is Scene.
The current version of the product is Version 3. The Version 2 is also available, but please note that the QA_Flag data has been changed.
