description: GCOM-C/SGLI L2 Snow and Ice Physical Properties (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 Grain size of Shallow Layer (SGSL), Snow and Ice Surface Temperature (SIST) and QA flag.SGSL data is the optical equivalent snow grain size of shallow layer estimated based on neural network method using observed radiance in the visible and near infrared region. The physical quantity unit is micro-meter.SIST data is the skin temperature of snow and ice estimated based on split-window method using observed brightness temperature in the thermal infrared region. The physical quantity unit is Kelvin.QA_flag shows the flag of estimation quality and retrieval conditions. 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.
