Resumo: It was carried out a comparative study of the following meteorological elements: air temperatures (maxT, minT, avrT), air relative humidity (avrRH) and atmospheric pressure (atmP). They were registered simultaneously in two meteorological stations: Conventional (CMS) and Automatic (AMS), in Maringá, state of Paraná, from 03/01/1999 to 12/31/2001. The stations’ data were evaluated through the determination coefficient (R²), Willmott's index of agreement (d) and linear regression angular coefficient errors (&epsílon;). After data analysis, we were concluded that maxT, minT, avrT and avrRH presented a significant agreement between CMS data and AMS data. However the avrRH values of AMS, obtained by electronic sensor, were 2% larger than the corresponding values of CMS. The atmP values presented low errors but with significant differences, which were associated to a difference of altitude (28m) among the two stations.

Os dados entre as respectivas estações foram comparados através do coeficiente de determinação (R2), do índice de concordância de Willmott (d) e por meio do erro () associado ao coeficiente angular da reta de regressão. Após a análise dos dados, concluiu-se que os elementos meteorológicos Tmax, Tmed, Tmin e URmed apresentaram significativa concordância entre os dados observados na EMC e na EMA. Os valores da URmed obtidos pelo sensor eletrônico da EMA foram 2% maiores que os mesmos obtidos pelo sensor da EMC, estando esse erro dentro da faixa de precisão dos sensores. Apesar dos baixos erros, os dados de Patm apresentaram diferenças significativas, contudo essa defasagem numérica deve-se à diferença de altitude (28m) das localidades onde se situam a EMC e a EMA.Universidade Estadual De Maringá2008-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/222010.4025/actascitechnol.v25i2.2220Acta Scientiarum.
