    Estimating the planetary boundary layer height from radiosonde and doppler lidar measurements in the city of São Paulo - Brazil
    2018 - MARQUES, MARCIA T.A.; MOREIRA, GREGORI de A.; PINERO, MACIEL; OLIVEIRA, AMAURI P.; LANDULFO, EDUARDO
    This study aims to compare the planetary boundary layer height (PBLH) values estimated by radiosonde data through the bulk Richardson number (BRN) method and by Doppler lidar measurements through the Carrier to Noise Ratio (CNR) method, which corresponds to the maximum of the variance of CNR profile. The measurement campaign was carried during the summer of 2015/2016 in the city of São Paulo. Despite the conceptual difference between these methods, the results show great agreement between them.

    Rehearsal for assessment of atmospheric optical properties during biomass burning events and long-range transportation episodes at metropolitan area of São Paulo-Brazil (RAPEL)
    2018 - LOPES, FABIO J.S.; GUERRERO-RASCADO, JUAN L.; BENAVENT-OLTRA, JOSE A.; ROMAN, ROBERTO; MOREIRA, GREGORI A.; MARQUES, MARCIA T.A.; SILVA, JONATAN J. da; ALADOS-ARBOLEDAS, LUCAS; ARTAXO, PAULO; LANDULFO, EDUARDO
    During the period of August-September 2016 an intensive campaign was carried out to assess aerosol properties in São Paulo-Brazil aiming to detect long-range aerosol transport events and to characterize the instrument regarding data quality. Aerosol optical properties retrieved by the GALION - LALINET SPU lidar station and collocated AERONET sunphotometer system are presented as extinction/ backscatter vertical profiles with microphysical products retrieved with GRASP inversion algorithm.

    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.
