Artigo IPEN-doc 27744 Evaluation of atmospheric aerosols in the metropolitan area of São Paulo simulated by the regional EURAD-IM model on high-resolution2021 - DUARTE, EDICLE de S.F.; FRANKE, PHILIPP; LANGE, ANNE C.; FRIESE, ELMAR; LOPES, FABIO J. da S.; SILVA, JONATAN J. da; REIS, JEAN S. dos; LANDULFO, EDUARDO; SILVA, CLAUDIO M.S. e; ELBERN, HENDRIK; HOELZEMANN, JUDITH J.We present a high-resolution air quality study over São Paulo, Brazil with the EURopean Air Pollution Dispersion - Inverse Model (EURAD-IM) used for the first time over South America simulating detailed features of aerosols. Modeled data are evaluated with observational surface data and a Lidar. Two case studies in 2016 with distinct meteorological conditions and pollution plume features show transport (i) from central South America, associated to biomass burning activities, (ii) from the rural part of the state of São Paulo, (iii) between the metropolitan areas of Rio de Janeiro and São Paulo (MASP) either through the Paraíba Valley or via the ocean, connecting Brazil's two largest cities, (iv) from the port-city Santos to MASP and also from MASP to the city Campinas, and vice versa. A Pearson coefficient of 0.7 was found for PM10 at MASP CENTER and EURAD-IM simulations vary within the observational standard deviation, with a Mean Percentual Error (MPE) of 10%. The model's vertical distributions of aerosol layers agree with the Lidar profiles that show either characteristics of long-range transported biomass burning plumes, or of local pollution. The distinct transport patterns that agree with satellite Aerosol Optical Death and fire spot images as well as with the ground-based observations within the standard deviations, allows us exploring patterns of air pollution in a detailed manner and to understand the complex interactions between local to long-range transport sources.Artigo IPEN-doc 27704 Aerosol properties in the atmosphere of Natal/Brazil measured by an AERONET Sun-photometer2021 - OLIVEIRA, DANIEL C.F. dos S.; MONTILLA-ROSERO, ELENA; LOPES, FABIO J. da S.; MORAIS, FERNANDO G.; LANDULFO, EDUARDO; HOELZEMANN, JUDITH J.We analyzed data measured by a Sun-photometer of the RIMA-AERONET network with the purpose to characterize the aerosol properties in the atmosphere over Natal, state capital of Rio Grande do Norte, at the coast of Northeast Brazil. Aerosol Optical Depth, Ångström Exponent, Volume Size Distribution, Single Scattering Albedo, Complex Refractive Index, Asymmetry Factor, and Precipitable Water were analyzed from August 2017 to March 2018. In addition, MODIS and CALIOP observations, local Lidar measurements, and modeled backward trajectories were analyzed in a case study on February 9, 2018, that consistently confirmed the identification of a persistent aerosol layer below 4 km agl. Aerosols present in the atmosphere of Natal showed monthly mean Aerosol Optical Depth at 500 nm below 0.15 (~ 75%), monthly means of the Ångström Exponent at 440–670 nm between 0.30 and 0.70 (~ 69%), bimodal Volume Size Distribution is dominantly coarse mode, Single Scattering Albedo at 440 nm is 0.80, Refractive Index - Real Part around 1.50, Refractive Index - Imaginary Part ranging from 0.01 to 0.04, and the Asymmetry Factor ranged from 0.73 to 0.80. The aerosol typing during the measurement period showed that atmospheric aerosol over Natal is mostly composed of mixed aerosol (58.10%), marine aerosol (34.80%), mineral dust (6.30%), and biomass burning aerosols (0.80%). Backward trajectories identified that 51% of the analyzed air masses over Natal originated from the African continent.Artigo IPEN-doc 21762 Latin American Lidar Network (LALINET) for aerosol research: diagnosis on network instrumentation2016 - GUERRERO-RASCADO, J.L.; LANDULFO, EDUARDO; ANTUNA, JUAN C.; BARBOSA, HENRIQUE de M.J.; BARJA, BORIS; BATIDAS, ALVARO E.; BEDOYA, ANDRES E.; COSTA, RENATA F. da; ESTEVAN, RENE; FORNO, RICARDO; GOUVEIA, DIEGO A.; JIMENEZ, CRISTOFER; LARROZA, ELIANE G.; LOPES, FABIO J. da S.; MONTILLA ROSERO, ELENA; MOREIRA, GREGORI de A.; NAKAEMA, WALTER M.; NISPERUZA, DANIEL; ALEGRIA, DAIRO; MUNERA, MAURICIO; OTERO, LIDIA; PAPANDREA, SEBASTIAN; PALLOTA, JUAN V.; PAWELKO, EZEQUIEL; QUEL, EDUARDO J.; RISTORI, PABLO; RODRIGUES, PATRICIA F.; SALVADOR, JACOBO; SANCHEZ, MARIA F.; SILVA, ANTONIETA
