Product Summary

GCOM-C/SGLI L3 Map Normalized water leaving radiance (NWLR L412) (1-Month,1/24 deg) 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 3 products are defined to be products derived from Level 1B and Level 2 products by statistically processing the Level 1B and Level 2 products in time and space domains.
This dataset is 1 month map-projected statistics product. This dataset includes NWLR_412: the upwelling radiance just above the sea surface at 412 nm and QA_Flag. The physical quantity unit is W/m^2/str/um. The stored statistics values are average (AVE) and quality flag (QA_flag).
The provided format is HDF5. The Spatial resolution is 1/24 degree. The statistical period is 1 month, also 1 day and 8 days statistics are available. The projection method is EQR. The generation unit is Global. The current version of the product is Version 3. The Version 2 is also available.
