This equipment is installed at Southern Space Observatory OES/CRSPE/INPE MCT (29.4°S, 53.8°W) located at São Martinho da Serra RS, Brazil, and it performs the total column gas trace measurements as ozone and sulphur dioxide for five specific wavelengths: 306.3, 310.1, 313.5, 316.8, 320.1 nm. The AOT were calculated from January 1997 to December 2006. Data analysis showed the presence of AOT high values, named here as aerosol peaks, for the region in some days of the period. The occurrence of these peaks was analyzed in accordance with each month for the whole period. %@group RSU-INPE-MCT-BR %@group RSU-INPE-MCT-BR %@group %@group DGE-INPE-MCT-BR %@group RSU-INPE-MCT-BR %@group RSU-INPE-MCT-BR %@group RSU-INPE-MCT-BR %@group RSU-INPE-MCT-BR %@affiliation Centro Regional Sul de Pesquisas Espaciais – CRSPE/INPE – MCT %@affiliation Centro Regional Sul de Pesquisas Espaciais – CRSPE/INPE – MCT %@affiliation Laboratório de Ciências Espaciais de Santa Maria – LACESM/CT – UFSM %@affiliation Instituto Nacional de Pesquisas Espaciais (INPE) %@affiliation Centro Regional Sul de Pesquisas Espaciais – CRSPE/INPE – MCT %@affiliation Centro Regional Sul de Pesquisas Espaciais – CRSPE/INPE – MCT %@affiliation Centro Regional Sul de Pesquisas Espaciais – CRSPE/INPE – MCT %@affiliation Centro Regional Sul de Pesquisas Espaciais – CRSPE/INPE – MCT %I Sociedade Brasileira de Geofísica %D 2007 %A Possani, Germano, %A Schuch, Nelson Jorge, %A Pinheiro, Damaris Kirsch, %A Alvalá, Plinio Carlos, %A Soares, Ana Marceli, %A Pereira, Nadiara, %A Bertagnolli, Caroline, %A Santos, Luana Serafini dos, %@area CEA %T Análise Picos de Espessuras Ópticas de Aerossóis sobre o Observatório Espacial do Sul (29.4° S, 53,8° O) de 1997 a 2006 %F self-archiving-INPE-MCTIC-GOV-BR %@versiontype publisher %S Proceedings %@secondarykey INPE--PRE/ %2 sid.inpe.br/mtc-m17@80/2007/11.20.23.48.44 %@documentstage not transferred %1 Sociedade Brasileira de Geofísica %C Rio de Janeiro, RJ %@holdercode {isadg {BR SPINPE} ibi 8JMKD3MGPCW/3DT298S}
