Message

Meteorology student at the Federal University of Pará (UFPA). I am currently a fellow of the Institutional Program for Scientific Initiation Scholarships (PIBIC) and a member of the research group in Atmospheric Sciences. At PIBIC, he conducts guided research on spatialized estimates of optical properties of aerosol particles on the AQUA and TERRA space platforms. The research group is focused on Applied Meteorology and Atmospheric Aerosols, aiming to answer questions related to the effects of aerosols in an underexplored region of the Amazon. The research is concentrated in the Eastern Amazon. The main contributions will assess the effects of anthropogenic emissions on the radiative balance in the atmosphere.
