GCOM-C/SGLI L3 Map Aerosol angstrom exponent (8-Days,1/12 deg)
Listed in NASA Earthdata CMR
GCOM-C/SGLI L3 Map Aerosol angstrom exponent (8-Days,1/12 deg) 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. Level 3 products are defined to be products derived from Level 1B and Level 2 products by statistically processing the Level 1B and Level 2 products in time and space domains.This dataset is 8 days map-projected statistics product.

This dataset includes aerosol angstrom exponent. The physical quantity unit is dimensionless. The stored statistics values are average (AVE) and quality flag (QA_flag).
A common aerosol optical model is used for the retrieval over ocean and land, and the model is determined based on the skyradiometer observation data. While fixing the particle shape, real part of complex refraction index and size distributions of large and small particle, the fraction of small particle and complex refraction index (in terms of SSA) are assumed to be variable.The provided format is HDF5. The Spatial resolution is 1/12 degree.
The statistical period is 8 days, also 1 day and 1 month statistics are available. The projection method is EQR. The generation unit is Global.
The current version of the product is Version 3. This product integrates L3 Map Aerosol angstrom exponent over ocean (AAEO), L3 Map Aerosol angstrom exponent over land (near UV) (AAEL) and L3 Map Aerosol angstrom exponent over land (Polarization) (AAEP) from version 3.
