I am a Master's student at the Institute of Physics, University of São Paulo (USP), conducting research focused on the characterization of the optical and microphysical properties of atmospheric aerosols using remote sensing techniques. My research focuses on investigating the angular dependence of polarized solar radiation, using observations from the HARP2 instrument aboard NASA's PACE mission, combined with measurements from the AERONET network. The study aims to analyze and compare these observations to establish relationships between the angular polarimetric response and aerosol properties, as well as to investigate the influence of surface radiative properties on the observed signal over continental and oceanic regions.
