Abstract

The Rio de Janeiro Metropolitan Region (RJMR) has the second largest concentration of people, vehicles, industries and other air pollutant sources of Brazil, suffering from chronic air pollution problems. A high resolution (1×1 km) spatial distribution of aerosols over the RJMR was obtained based on reflectance measured by MODIS (Moderate Resolution Spectrometer) sensors, on board of EOS‐Terra platform, operated by NASA/GSFC. Aerosol optical thicknesses were retrieved from these measurements using the software SBDART (Santa Barbara DISORT Atmospheric Radiative Transfer Model) and an algorithm developed in a previous study.
