Data quality of automatic meteorological stations located in three states of Mexico

Abstract

The objective of the present work was to apply some procedures to evaluate the quality of data coming from different automatic meteorological stations (EMA) located in three states of the Mexican Republic. Daily meteorological data were obtained from automatic stations: one in the State of Mexico, five in Guanajuato, and one in Sinaloa. The procedures that were used were: for the maximum, average, and minimum temperature and global radiation, the flexible range test or meteorological event was applied; for the temperature and relative humidity variables, the internal consistency test was used;
to the variable temperature, the thermal jump and the zeros test were applied; to the relative humidity, the internal consistency, and the persistence test. For the station located in Sinaloa, for the variable daily global radiation, on the flexible range test, it presented 23.25 % of erroneous data. The results of the procedures applied to historical data of the EMAs support determining the reliability of the meteorological information of these for use.
