In this study, the atmospheric (RAMS) and scavenging (B.V.2) models were used, in order to simulate sulfate concentrations in rainwater using scavenging processes as well as the local atmospheric conditions obtained within the LBA Project in the State of Rondonia, during a dry-to-wet transition season. Two case studies were conducted. The RAMS atmospheric simulation of these events presented satisfactory results, showing the detailed microphysical processes of clouds in the Amazonian region. On the other hand, with cloud entrainments, observed values have been overestimated. Modeled sulfate rainwater concentration, using exponential decay and cloud heights of 16 km and no entrainments, presented the best results, reaching 97% of the observed value. The results, using shape parameter 5, are the best, improving the overall result. %@mirrorrepository sid.inpe.br/mtc-m18@80/2008/03.17.15.17.24 %8 feb. %N 2 %T Two case studies of sulfate scavenging processes in the Amazon region (Rondônia) %@secondarytype PRE PI %K numerical modeling, Amazonia reion, LBA project. %@group %@group %@group DMD-CPT-INPE-MCT-BR %@e-mailaddress deicy.farabello@cpetec.inpe.br %@secondarykey INPE--PRE/ %U DOI: 10.1016/j.envpol.2008.08.016 %@issn 0269-7491 %2 sid.inpe.br/mtc-m18@80/2009/07.28.16.45.09 %@affiliation Civil Engineering Department, UFRJ/COPPE/PEC/LAMCE, Athos da Silveira Ramos, 149, 21941-909 Rio de Janeiro, Brazil %@affiliation Department of Atmospheric Sciences, University of Sa˜o Paulo (IAG/USP), Brazil %@affiliation Instituto Nacional de Pesquisas Espaciais (INPE) %B Environmental Pollution %P 637-645 %4 sid.inpe.br/mtc-m18@80/2009/07.28.16.45 %D 2009 %V 157 %@doi 10.1016/j.envpol.2008.08.016 %A Silva, M.
