Abstract:
The automatic quality control for real time data of automatic weather stations i s made by using the climatic extreme range check, internal consistency check, ti me consistency check and spatial consistency check. In order to reduce the numbe r of false check for meteorological element, a method which can check the sudden drop of temperature in single station is developed. Using the data of automatic weather stations in Hubei Province, the data are checked and the checked rate of error is 0.48‰. The data quality has been largely improved by using the abov ementioned method, especially spatial consistency check method based on the spatial interpolation. During the testing period, the quality control fo r an hour dada of 81 weather stations in Hubei Province can be completed within 2 minutes.
