| Abstract | Neste trabalho utilizou-se a tecnica MICE (do ingles “Multivariate Imputation by Chained Equations”) para imputacao de dados diarios de variaveis meteorologicas, para series temporais provenientes de 96 estacoes convencionais do INMET, entre periodo de 1961 e 2012, para em seguida aplicar os testes de um sistema de controle de qualidade desenvolvido para deteccao, correcao e possivel substituicao de dados suspeitos. Tanto as tecnicas de preenchimento de falhas utilizadas, quanto do sistema de controle de qualidade, evidenciaram ser possivel solucionar dois dos maiores problemas encontrados nas series temporais de dados diarios medidos em estacoes meteorologicas: a geracao de valores plausiveis, para cada variavel de interesse, a fim de sanar a ausencia de observacoes, como detectar e permitir a devida correcao, a valores suspeitos provenientes das observacoes. A B S T R A C T In this work we used the technique MICE ("; Multivariate imputation by Chained Equations ";) for allocating daily data of meteorological variables for time series from 96 conventional stations of INMET , between 1961 and 2012 , and then to apply the tests for a system of quality control developed for detection , correction and possible replacement of suspect data . Both gap filling technique used , as the system of quality control , showed to be possible to solve two major problems encountered in time series of daily data measured at weather stations : the generation of plausible values for each variable of interest , the order to remedy the lack of observations , how to detect and allow correction due to suspicious values from the observations . |
