Abstract
Ground weather stations play a vital role in understanding and predicting the weather. The information they collect is used to analyze climate patterns, issue early warnings about extreme phenomena, among others. In Cuba, where vulnerability to disasters is high, the integrity of meteorological data is even more critical. In this research, a Quality Control System for surface observations was designed. For this purpose, the Surface Meteorological Observations Management System was used, which took into account aspects of climatology of the measured variable and statistical analysis of the data. The results showed that if when entering the measured data in the acquisition system, it is detected that it is an instrumentally impossible or incoherent value, it prevents its entry, and if it is an unlikely value, it generates a warning message. Whenever the data is admitted by the system, a flag is generated that makes it easier for data users to know its quality to decide whether or not it is suitable for their application.
