GCOM-C/SGLI L2 Statistics-TOA radiance (1-Month,250m)
Listed in NASA Earthdata CMR
GCOM-C/SGLI L2 Statistics-TOA radiance (1-Month,250m) is obtained from the SGLI sensor onboard GCOM-C and produced by the Japan Aerospace Exploration Agency (JAXA).
Description
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.Using the Level2 tile product of precise geometric corrected TOA radiance as input, the clear region mosaic data for 8-days or 1-month is stored in the output product. The region definition and spatial resolutions of the output product are kept the input data.

This dataset includes Top of atmosphere radiance of each bands and Land water flag. Using the Level2 tile product of precise geometric corrected TOA radiance (Daily, Tile, 250 m resolution) as input, the clear region mosaic data for 1-month is stored in the output product. The region definition and spatial resolutions of the output product are kept the input data.
Maximum absolute NDVI composite method is used for mosaicking process. In this method output data store the TOA radiance of a single observation day on which the value of |NDVI-alpha| becomes the maximum during the temporal interval (1-month).The physical quantity unit is W/m^2/str/mm. The provided format is HDF5.The spatial resolution is 250 m.
The statistical period is 1 month also 8 days statistics is available. The projection method is EQA. The generation unit is Tile.
The current version of the product is Version 2. The Version 3 is also available
