  • GCOM-C/SGLI L2 Statistics-Land Surface Reflectance(RV03) (8-Days, 250m) is obtained from the SGLI sensor onboard GCOM-C and produced by the Japan Aerospace Exploration Agency (JAXA). Using the Level2 atmospheric corrected land surface reflectance tile product as input, BRDF correction is performed for the land surface in clear region using data of multiple days, and the reflectance equivalent to that at nadir view direction is stored in the output product. The region definition and spatial resolutions of the output product are kept the input data. In 8-days processing, the land surface reflectance data of the past 24 days, respectively are fitted to generate appropriate BRDF models with the correction coefficients. 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.This dataset includes of following SDs (Center Wavelength is correspond to channel name as same as L1B): Rs_VN03_AVE is Normalized surface reflectance [unit: none]Rs_VN03_Date is Date identificator of surface reflectance [unit: none]Rs_VN03_MAX is Maximum of surface reflectance [unit: none]Rs_VN03_MIN is Minimum of surface reflectance [unit: none]Rs_VN03_Ninput is Input data number of surface reflectance [unit: none]Rs_VN03_Nused is Used data number of surface reflectance [unit: none]Rs_VN03_QA_flag is quality flag about the statistics and BRDF regression [unit: none]Rs_VN03_RMS is RMS of BRDF model regression of surface reflectance [unit: none]Rs_VN03_c0-2 are c0, c1, and c2 coefficients of surface reflectance [unit: none]The provided format is HDF5. The spatial resolution is 250 m. The statistical period is 8 days also 1 month statistics is available. The projection method is EQA. The generation unit is "Tile". The current version of the product is Version 3. The Version 2 is also available.
