GCOM-C/SGLI L2 Snow and Ice Cover Extent (1km)

GCOM-C/SGLI L2 Snow and Ice Cover Extent (1km) dataset is obtained from the SGLI sensor onboard GCOM-C produced by the Japan Aerospace Exploration Agency (JAXA). GCOM-C is Sun-synchronous sub-recurrent orbit satellite launched on December 23, 2017 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 granule scene and global (tile) data of physical quantity derived from Level-1B or Level-2 products and ancillary data such as meteorological data and various additional data related to the physical quantity.This dataset includes Snow and Ice Cover Extent (SICE).SICE data is the classification flags of cloud, land, open water and snow and sea ice. The flags were determined using typical characteristics of reflectance based on the radiative transfer simulations. The physical quantity unit is dimensionless. The provided format is HDF5. The projection method is EQA and the generation unit is Tile. The current version of the product is Version 3. The Version 2 is also available.
