Aerosls are emitted by a several sources, these can be antropogenic – emitted by human activities - or natural.Their sudies are an important, because its impacts on the dynamics of the Earth’s atmosphere are huge. The study area have one of the most important industrial complex in the state of Sao Paulo. In the past the city of Cubatão was known as “death valey”, due to the environmental problems caused by the high levels of pollutants that was emitted by the industries. Following this event, regulatory laws on atmospheric emissions were developed, both at the state and federal levels. Today, although Cubatão has lower levels of pollution and controlled industrial emissions, but it is possible to observe overcoming air quality standards. Based on the presented context, the present work aims to conduct a study of the dispersion of aerosols in the region of Cubatão-SP using several techniques, such as: remote sensing (elastic lidar and wind lidar), satellite data, air quality information and also simulations of air masses using a model.
Correlation study between air quality data and the Lidar system in Cubatao, Sao Paulo
2017 - ARAUJO, ELAINE C.; ANDRADE, IZABEL da S.; MACEDO, FERNANDA de M.; CORREA, THAIS; SALANI, MARIA H.G. de A.; COSTA, RENATA F. da; RAMOS, SERGIANA dos P.; MARQUES, MARCIA T.A.; LOPES, DANIEL S.; GUARDANI, MARIA L.G.; LANDULFO, EDUARDO; GUARDANI, ROBERTO
We present here the results of two methods with a scanning multiwavelength elastic lidar system and Beta Ray method (CETESB) realized in an industrial area. The objective is a comparer of these two methods to identify fixed sources of aerosol and to monitor plume dispersion. The results of the two aligned techniques indicate that can provide information on the concentration, spatial and temporal distribution of aerosol.
Monitoring the industrial sources of aerosol in Cubatao, Brazil, using a scanning elastic lidar and a lidar doppler
2018 - COSTA, RENATA F. da; MARQUES, MARCIA T.A.; MACEDO, FERNANDA de M.; ANDRADE, IZABEL da S.; ARAUJO, ELAINE C.; CORREA, THAIS; SALANI, MARIA H.G. de A.; LOPES, DANIEL S.; GUARDANI, MARIA L.G.; LANDULFO, EDUARDO; GUARDANI, ROBERTO
Field campaigns with a scanning multiwavelength elastic lidar coupled with a Doppler system to monitor industrial atmospheric aerosol emissions were carried out, with the objective of monitoring aerosol emission sources and plume dispersion. Since the technique provides information on the spatial and temporal distribution of aerosol concentration, the implementation of a systematic monitoring procedure is proposed as a valuable tool in air quality monitoring applied to regions of interest.
Monitoring of pollutants and environmental impact dispersion in santos estuary by the technique LIDAR
2016 - SALANI, MARIA H.G. de A.; LANDULFO, EDUARDO
The atmosphere is a medium that deforms easily through its movements carrying the gaseous compounds and particles away from places where they were generated. In big cities, due to its complex structure, it is very difficult to identify and quantify their polluting sources, which impacts directly on questions regarding the reduction of pollutants’ emission, that are aimed to improve the health of the population. Estuaries may suffer indirect contamination through atmospheric deposition, which can be one of the main forms of contamination of the aquatic environment. This study seeks to identify and to quantify the presence of suspended particulate material in the port of Santos area, which receives pollution of emission of vehicles, ships, industrial operations. The chosen area for monitoring, in order to quantify and to measure this particulate material, was the estuary of the Port of Santos, located in the state of São Paulo, in the city of Santos, Lat. 23º59’24’’S e Long. 46º20’12’’W. The methodology used is the remote sensing technique known as laser lidar to monitor, in near real time, atmospheric emissions of particulate matter and trace gases, from the estuary of the Port of Santos-SP. The lidar operates a commercial pulsed-laser transmission system, and its configuration offers complete overlap between the system's field of vision and the laser beam at an altitude of approximately 180m. It is intended to find a methodology capable of monitoring the emissions of particulate material in the air, based on the processing of data from the measurement performed by the Lidar’s system. It allows the identification of the sources and characteristics (size and type) of the particulate material; as well as the pattern of its dispersion can be identified and studied.
