Abstract

The objective of the research project is the temporal and spatial characterization of the aerosol in the Metropolitan Region of São Paulo (MRSP) and comparison with satellite data. The Environmental Company of São Paulo State (CETESB) has a network of air quality monitoring in the metropolitan region, and it is possible to know the concentration of particulate matter in several regions, over time, since the network has been operating for many years. In this project we intend to study the concentration of fine and coarse particulate matter in the region in the last 5 years, its spatial distribution, relation with land use and occupation, and comparison with satellite data. A first step will be developed by analyzing CETESB air quality network data, then comparing it with land use and occupation over the study period and then comparing it with satellite data. The Moderate-Resolution Imaging Spectroradiometer (MODIS) is an instrument launched into Earth's orbit by NASA in 1999 onboard the Terra satellite and in 2002 onboard the Aqua satellite. In the "Atmosphere" line, among the products is the Aerosol Optical Depth (AOD), which gives an idea of the concentration of the particles. Over the years, for periods of satellite data, it will be possible to compare surface data with satellite data, ie comparison of surface concentration with one of its optical properties, which is Aerosol Optical Depth (AOD).
