| 摘 要： | 全球观测资料质量监视评估系统是为监视评估国家气象中心所接收的全球气象观测资料的质量而设计开发的。该系统以资料同化的6小时预报场为背景场，计算观测资料与背景场的偏差；运用质量控制技术排除观测资料中的可能是错误的资料；实时和非实时地统计分析各类观测报告的状况和观测资料的质量。采用的质量控制技术和统计分析方法都尽量和国际上发达气象中心相一致。所有产品都以图表形式在气象系统内部web网页上发布。该系统应用于日常观测资料质量监视评估及中国区域探空资料问题的详细分析、探空站综合评分、探空观测资料归档、探空观测资料偏差订正效果检验、L波段探空资料质量分析等，取得了显著效果。对加强观测业务管理、保证观测资料质量、改进观测技术发挥了积极的作用。

| Abstract: | The observation monitoring and evaluating system in NMC/CMA is described. This system includes the function of data processing, data quality control, bias statistics and analysis, products releases etc. The complex quality control and advanced evaluation tech- nique are adopted. As an operational system, some observation problems are found and have been improved. The products also were used in verification of the bias correction scheme for 59 radiosonde and in the quality analyses for L-band digital radiosonde. A great contribution was made by the system on the management of observation operational, the improvement of observation quality and the application of observation data. |
