Ver.2 Update

  • The accuracy is improved. (Detail (In Japanese) (2020/06/18 update))
  • Product Change
    • RSRF: Shortwave radiation (SWR) is added.
    • LAI: Change from Understory_NDVI to Overstory_LAI
    • SST: GHRSST required SD (data set) is added.
  • Others
    • several minor changes
  • (Note 1)
    • Version number of ALL products will be changed from "1xxx" to "2xxx".
    • G-Portal (FTP) directory for standard products will be changed from "1" to "2".
      The directory of near-realtime products is not changed (only the file name is changed).

      GC1SG1_20200105A01D_T0112_L2SG_CLFGK_2000.h5
  • (Note 2) (2020/06/11 Update)
    1. Because of the process system change, statistics products (8D, 1M) with insufficient statistical period will be produced. (TBD)
    2. L2 RSRF accuracy will be degraded for maximum 3 months because of the insufficient input data at the version transition.
    3. ALL land and atmosphere products will be affected by the RSRF accuracy because they use RSRF as an input.
    Sorry for your inconvenience.
