GCOM-C/SGLI L2 Global Top of atmosphere radiance (clear sky) is obtained from the SGLI sensor onboard GCOM-C and produced by the Japan Aerospace Exploration Agency (JAXA). GCOM-C is a Sun-synchronous sub-recurrent orbit satellite launched on December 23, 2017. It mounts SGLI sensor to observe long-term geophysical conditions based on 28 variables, including aerosol and vegetation, out of four Earth subsystems: atmosphere, land, ocean, and cryosphere. These data are helpful to improve the global warming prediction accuracy. The SGLI has a swath of 1150 km in the visible band and 1400 km in the infrared band. Level 2 products consist of derived physical variables based on Level 1B products, such as meteorological data. The contents are each band's Top of atmosphere radiance (W/m^2/str/mm) and Land water flag. TOA radiances are initially derived from daily 1-km resolution TOA radiance and cloud flag products, which spatial coverage is Tile. Consequently, this product is generated from the clear (cloud-free) pixels. The provided format is HDF5. The spatial and temporal resolutions are 1/24 deg and daily, respectively. The projection method is EQA. The spatial coverage is Global. The current version of the product is Version 3. The Version 2 is also available
