Abstract

This work describes an algorithm for aerosol retrieval focusing on the second global imager (SGLI) mounted on the forthcoming global change observation mission - 1st climate satellite (GCOM-C1). The SGLI has a function to measure semi-Stokes components (I, Q, and U) of the Earth's reflectances at red (678 nm) and near infrared (868 nm) with large tilting angle (±45 deg.) along track direction. The SGLI also measures total reflectance from nadir looking position from near UV (380 nm) to far infrared (12 μm). The aerosol retrieval algorithm for the SGLI uses two-channel polarization information from slant path direction as well as nadir looking reflectance at blue channel (443 nm) to estimate aerosol optical thickness, Ångström exponent, and single scattering albedo of particles. The algorithm is tested by the polarization and directionality of the Earth's reflectances (POLDER) measurements.
