气象辐射数据质量控制

气象辐射观测数据是气象业务、服务和科学研究的基础,其质量控制很重要。本文通过对近几年甘肃省地面气象辐射观测记录中出现的问题进行梳理,根据地面气象观测规范要求和实际工作中的审核经验,对气象辐射观测记录的质量控制方法及容易发生异常的地方进行总结,以期对台站提高辐射月报表数据文件的质量提供参考,对从事省级气象数据质量控制工作尤其是刚从事该项工作的人员的提供有益的帮助。结果显示:仪器正常时的异常记录参考云量云状、能见度、天气现象、定时降水量等气象要素进行人工判别,是现阶段气象辐射数据质量控制的最有效办法;对于仪器故障时的异常记录的判别要分情况考虑,遵从业务规定的方法取代异常值和缺测值;对于记录中容易出错的其他问题,则需要台站观测员及质量控制人员加强业务学习,总结工作经验,避免类似问题再次出现。

Quality Control of Meteorological Radiation Data

Meteorological radiation observation data is the foundation of meteorological operations, service and scientific researches, so its quality control is very important. By analyzing the problems from the surface meteorological radiation observation records of Gansu Province in recent years, according to the surface meteorological observation specification requirements and actual work experiences, this paper summarizes the quality control methods of meteorological radiation observation records and abnormal values, aiming to provide a reference for stations in improving the quality of the monthly radiation data file and provide some useful help for the provincial meteorological data quality control, especially for the new staff. The results show that when the instrument is normal, abnormal records need to be judged manually in combination with the meteorological elements at that time, which is the most effective way of meteorological radiation data quality control at the present stage. When the instrument fails, the abnormal records should be considered according to different situations; for example, abnormal values and missing values should be replaced in accordance with the relevant operation regulations. For the problems prone to errors in the records, the observers and quality control personnel are required to improve professional skills, summarize work experiences, and avoid similar problems.
