Abstract:
The city densification and, consequently, the potential polluting activities have increased significantly in the last decades, compromising the air quality. Thus, it is necessary to know this scenery to model the pollution behavior and its respective pattern in each region of the Federal District. So, the main goal of this study was to analyze the Aerosol product available by National Aeronautics and Space Administration (NASA) at the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor (TERRA). With these preexisting data, it was possible to analyze the aerosol (AOD) distribution from 2010 and the optical depth. These data were integrated to the processed values of Total Particles in Suspension (PTS) of the eight air quality monitoring stations variably distributed in the Federal District, with two of them (714 south and HUB) kept and managed by the Interdisciplinary Center of Transport Studies (Centro Interdisciplinar de Estudos em Transportes - Ceftru/UnB), correlating the month of October 2010. The study showed that the region of BrasÃlia downtown and the surroundings of the Fercal region, overall, were the ones that kept most of the Aerosol Optical Depth (AOD) and the highest values of the Angström Exponent (AE), which can be attributed to the types of activities performed in these regions.
