description: GCOM-C/SGLI L2 Leaf Area Index dataset is obtained from the SGLI sensor onboard GCOM-C and produced by the Japan Aerospace Exploration Agency (JAXA). GCOM-C is Sun-synchronous sub-recurrent Orbit sattelite 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.Level 2 products are defined to be products composed of physical quantity data that is calculated based on Level 1B products and meteorological data, as well as various additional data related to the physical quantity data.This dataset includes Fraction of Absorbed Photosynthetically Active Radiation (FAPAR), Leaf Area Index (LAI), LAI for understory vegetation (Overstory_LAI) and quality flag (QA_Flag). FAPAR is the proportion of the effectively absorbed solar radiation by green vegetation in the photosynthetically active wavelength (the spectral region from 400 to 700 nm). It corresponds to the instantaneous FAPAR at the observation time of the GCOM-C satellite. The physical quantity is dimensionless. LAI is one half of the total green leaf area per unit ground surface area. It includes all overstory and understory green vegetation. The physical quantity is m^2/m^2. Overstory_LAI is LAI for overstory green vegetation (like leaves on trees). It excludes LAI for understory green vegetation like grasses. The physical quantity is m^2/m^2. The QA_flag shows flag of quality and observation condition.The provided format is HDF5. The spatial resolution is 250 m. 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
