摘要
自动气象站在使用中因雷击死机,标校、更换自动站传感器或电磁干扰,自动站传感器性能下降导致分钟、正点数据出现缺测,野值的情况经常发生。为确保气象记录的完整性和连续性,根据近两年对嘉兴地区地面气象信息化资料的审核实践,着重对地面气象信息化A、J文件数据缺测、野值及数据格式上出现错误及其他常见问题及处理方法进行探讨,以期在预、审核工作中减少错误,提高地面气象信息化资料的审核质量。
There occur frequently observation data errors induced by various causes, such as observation instrument breakdowns resulted from thunders and lightning, electromagnetism interruption from AMS sensor calibration and replacement, data missing from degraded sensor capability, etc. In order to ensure the complete and continuous records, based on two years experiences of data checking at the Jiaxing station, A-format and J-format data missing, wild values, errors in format, etc., are discussed, aiming to reduce the frequency of mistakes in data checking and to improve the data quality.
