抚顺市区域自动站温度资料质量控制方法研究

通过对区域气象自动站温度历史资料的统计分析,发现抚顺市区域站实时资料存在时钟突跳、部分站点要素及全要素报文缺测、部分站温度长时间异常等问题。应用气候学界限值检查、气候极值检查、时间一致性检查、空间一致性检查及格式检查等多种质量控制方法,实现了对区域站温度整点实时观测资料的自动化质量控制。保证了资料的可靠性,提升区域自动气象站实时资料的数据的可用性。

Through the statistical temperature historical data on the regional meteorological station automatic analysis,found that the real time data of Fushun City area station clock jump,part of the site factors and total factor message missing and some station problems such as abnormal temperature for a long time.The application of climatic limits several control methods of quality inspection,extreme value check,time consistency check and spatial consistency check and format checking,the realization of the regional station whole point temperature real-time observation data quality control automation.The reliability of data is guaranteed,and the availability of real-time data of regional automatic weather station is improved.
