Artigo IPEN-doc 22703 CHsub(4) concentrations over the Amazon from GOSAT consistent with in situ vertical profile data2016 - WEBB, ALEX J.; BOSCH, HARTMUT; PARKER, ROBERT J.; GATTI, LUCIANA V.; GLOOR, EMANUEL; PALMER, PAUL I.; BASSO, LUANA S.; CHIPPERFIELD, MARTIN P.; CORREIA, CAIO S.C.; DOMINGUES, LUCAS G.; FENG, LIANG; GONZI, SIEGFRIED; MILLER, JOHN B.; WARNEKE, THORSTEN; WILSON, CHRISTOPHERThe Amazon Basin contains large wetland ecosystems which are important sources of methane (CH4). Space-borne observations of atmospheric CH4 provide constraints on emissions from these remote ecosystems, but lack of validation precludes robust estimates. We present the rst validation of CH4 columns in the Amazon from the Greenhouse gases Observing SATellite (GOSAT) using dedicated vertical pro le measurements of CH4 over ve sites across the Amazon Basin. These aircraft pro les, combined with the TOMCAT stratospheric model, are vertically integrated allowing direct comparison to the GOSAT measurements. The absolute columns agree within uncertainties or show no signi cant di erence at three of the aircraft sites (-1.9 2.2 ppb and 3.6 4.3 ppb at one site with two di erent campaigns; and 3.6 1.7 ppb, and 6.6 2.6 ppb at the other two), whilst at two sites GOSAT XCH4 is shown to be slightly higher than aircraft measurements, by up to approximately 10 ppb in the most di ering case (8.1 2.1 ppb and 9.7 2.8 ppb). The seasonality in XCH4 seen by the aircraft pro les is also well captured. GOSAT observes elevated concentrations in the north-west corner of South America in the dry season and enhanced concentrations elsewhere in the Amazon Basin in the wet season; with the strongest seasonal di erences coinciding with regions in Bolivia known to contain large wetlands. Our results are encouraging evidence that these GOSAT CH4 columns are in good agreement with in situ measurements and can be reliably used to provide new insights into tropical methane emissionsResumo IPEN-doc 22314 Amazon vegetation response to anomalously dry and wet yars 2010 and 2011 derived from lower troposphere greenhouse gas balances2014 - GLOOR, EMANUEL U.; GATTI, LUCIANA; MILLER, JOHN B.; DOUGHTH, CHRIS; MALHI, YADVINDER; BASSO, LUANA S.; DOMINGUES, LUCAS G.; FREITAS, SAULO R.; ANDERSON, LIANA O.; PHILLIPS, OLIVER L.; LLOYD, JONResumo IPEN-doc 22297 4 anos de medidas de gases de efeito estufa no Brasil2014 - BORGES, V.F.; GATTI, L.V.; DOMINGUES, L.G.; CORREIA, C.S.C.; BASSO, L.S.; MARTINEWSKI, A.; MILLER, J.B.; GLOOR, E.U.Resumo IPEN-doc 22295 Estudo da emissão de Nsub(2)O da Bacia Amazônica2014 - CORREIA, CAIO S.C.; GATTI, LUCIANA V.; DOMINGUES, LUCAS G.; MARTINEWSKI, ALEXANDRE; BASSO, LUANA S.; BORGES, VIVIANE F.; GOMES, THIAGO B.; GLOOR, EMANUEL U.; MILLER, JOHN B.Resumo IPEN-doc 22294 O efeito da variação da precipitação e da temperatura no balanço de carbono da Bacia Amazônica2014 - GATTI, L.V.; DOMINGUES, L.G.; CORREIA, C.S.C.; BASSO, L.S.; BORGES, V.F.; FERNANDES, KAREN O.; GLOOR, M.; MILLER, J.B.Resumo IPEN-doc 22145 5 years brazilian greenhouse gases backround concentrations2015 - BORGES, V.; GATTI, L.; DOMINGUES, L.; CORREIA, C.; BASSO, L.; GLOOR, M.; MULLER, J.Resumo IPEN-doc 22142 Study of SF6 concentrations in Amazon Basin and brazilian coast2015 - BASSO, L.; GATTI, L.; BORGES, V.; CORREIA, C.; DOMINGUES, L.; MILLER, J.; GLOOR, M.Resumo IPEN-doc 21721 Amazon Basil: an important source of methane?2015 - BASSO, LUANA S.; GATTI, LUCIANA V.; CORREIA, CAIO S.C.; DOMINGUES, LUCAS G.; BORGES, VIVIANE F.; MILLER, JOHN B.; GLOOR, EMANUEL U.Artigo IPEN-doc 21680 Seasonality and interannual variability of CHsub(4) fluxes from the eastern Amazon Basin inferred from atmospheric mole fraction profiles2016 - BASSO, LUANA S.; GATTI, LUCIANA V.; GLOOR, MANUEL; MILLER, JOHN B.; DOMINGUES, LUCAS G.; CORREIA, CAIO S.C.; BORGES, VIVIANE F.Artigo IPEN-doc 18985 Influencia das massas de ar nas concentrações dos gases de efeito estufa na Costa Brasileira2012 - BORGES, VIVIANE F.; GATTI, LUCIANA V.; MARTINEWSKI, ALEXANDRE; BASSO, LUANA S.; CORREIA, CAIO S.C.; DOMINGUES, LUCAS G.; GLOOR, EMANUEL U.
