Abstract

The second global imager (SGLI) onboard the Japanese mission GCOM-C (2017) is a successor of ADEOS-2/GLI (2002). Both sensors have the same wavelength channels at 0.412 μm and 0.380 μm. The efficiencies of these data in detecting absorbing aerosols, such as biomass burning aerosols (BBA) or mineral dust (DUST), have been examined on a global scale in previous work¹ using GLI measurements. The purpose of this study was to examine the advantages of near-UV data collected using GLI with those of SGLI. The near-UV data not only detected absorbing aerosols but also utilized short wavelength infrared measurements to distinguish between BBA and DUST. Classification algorithms for aerosol types were suggested, as an understanding of aerosol types facilitates subsequent aerosol retrieval. Classified aerosols were then characterized based on radiation simulations with multi-spectral radiance and polarization measurements in the red and near-IR wavelength channels of SGLI.
