Resumen
In the last decades, several remote sensing platforms, i.e., spaceborne, aircraft and ground-based
measurement systems have been developed or improved to conduct studies of aerosol and cloud optical properties on
local and global scales, as well as to provide the scientific basis for understanding the Earth climate system. The
combination measurements between spaceborne sensors and ground-based instruments can helps to provide a better
understanding about the impact of aerosols on air quality and in the climate changes inside large cities. The
Metropolitan Area of S??o Paulo (MASP), one of the largest megacities in the world, frequently suffers with problems
related to the air quality. Concerned with the pollution scenario of MASP, several measurement campaigns were
conducted since 2012, specially, during the South hemisphere winter, period when the low temperatures and the low
level of precipitation contribute to the poor dispersion of aerosols. A multichannel Raman Lidar system and air
quality monitoring stations from University of S??o Paulo and Environment Agency of S??o Paulo State (CETESB)
were employed in order to monitor the increasing of aerosol load in the atmosphere. Satellite data from CALIPSO
and AQUA were applied to draws the pollution scenario and the most frequent aerosol type at MASP. This study
intend to present how the synergy between ground-based monitoring and satellite data can helps to improve the
studies the effects of particulate matter concentration in the air quality of MASP and the influence of aerosol from
biomass burning advected from large range distance of South American continent.
