WORKSHOP ON LIDAR MEASUREMENTS IN LATIN AMERICA, 11th
Resumo
Air pollution is recognized as a risk factor for health. The emission of toxic gases and particulates,
specially with diameter size smaller than 10 μm, into the atmosphere by industries is correlated with increasing
respiratory problems, mortality and cancer in some urban areas. Additionally the aerosol particles play an
important role in the Earth’s radiation budget and the understanding of their properties is important to address
their effects on the climate and weather conditions. In this study we will present some results of aerosol vertical
distribution retrieved using a mobile lidar system and the lidar system on board of the CALIPSO satellite
platform. The synergetic use of these platforms helped to understand the impact of the aerosol suspended in the
atmosphere in terms of its optical properties in two different sites between two main metropolitan areas of
Brazil, which are São Paulo and Rio de Janeiro. In order to obtain a statistical characterization of the aerosol
optical properties, level 2-version 4 data from CALIPSO were employed to retrieve the AOD and Lidar ratio
values at 532 nm for Volta Redonda and Lorena sites. Lorena campaign was performed during a very dry period
in the 2014 Southern hemisphere winter, where it detected the vertical distribution profile with several layers
detached from the aerosol boundary layer (ABL) on 26th of June 2014. Volta Redonda-RJ campaign performed
from the beginning of November until mid of December of 2018 provided detection of aerosol layers detached
from ABL on 4th of December of 2018. We will present a brief description of the experimental apparatus, the
data taking, the methodology and the main results which open up the possibility to investigate emission of toxic
gases and particulates at this region which has high contribution to local atmospheric pollution due to the
Presidente Dutra highway (BR 116), the Companhia Siderúgica Nacional (CSN) and other metallurgical and
cement factories.
