Neste trabalho utilizou-se a técnica MICE (do inglês “Multivariate Imputation by Chained Equations”) para imputação de dados diários de variáveis meteorológicas, para séries temporais provenientes de 96 estações convencionais do INMET, entre período de 1961 e 2012, para em seguida aplicar os testes de um sistema de controle de qualidade desenvolvido para detecção, correção e possível substituição de dados suspeitos. Tanto as técnicas de preenchimento de falhas utilizadas, quanto do sistema de controle de qualidade, evidenciaram ser possível solucionar dois dos maiores problemas encontrados nas séries temporais de dados diários medidos em estações meteorológicas: a geração de valores plausíveis, para cada variável de interesse, a fim de sanar a ausência de observações, como detectar e permitir a devida correção, a valores suspeitos provenientes das observações.

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.
