The Design of an Open Platform for Automatic Weather Stations on Real time Data Quality Control

The open platform for real time data quality control provides a unified interface and operating environment with the methods of quality control. The platform management system has the comprehensive ability to apply a variety of embedded quality control methods. Reports of the quality control from different system of quality control methods can also be analyzed comprehensively. With the platform, on the basis of interface and operating environment, technicians can independently carry out some operational trials and technological research about some quality control methods. Relevant quality control methods can also be integrated in the platform, so the methods with poor performance can be improved and replaced. Using the platform, pressure, temperature, relative humidity and precipitation data of 78 automatic weather stations are processed real time with 5 different quality control methods during the 3 month trial run in Zhejiang Province. Experiments show that using the comprehensive application of the platform can increase accuracy rate of the data error detection by 60%, and provide technical foundation for the research of promoting the quality control methods.
