随着中国气象局与民航总局AMDAR(Aircraft Meteorological Data Relay)合作项目的开展,气象部门获得的AMDAR观测资料逐渐增加.为获取高质量的AMDAR观测资料和充分合理地使用这些观测资料,必须对AMDAR观测资料时空分布、飞行状态信息、观测资料质量等信息进行充分调研分析,并开发设计出具有实际运用价值和能力的质量控制(QC)技术,使AMDAR观测资料在数值预报业务模式系统中发挥更大作用.AMDAR QC方案在参考国际先进AMDAR QC方案的基础上,根据AMDAR资料的特点和数值天气预报模式对AMDAR资料应用的要求而设计,其目的是解决AMDAR观测资料在数值预报中应用的质量问题.文中方案采用多种质量控制技术,其中包括气候极值检查、要素间一致性检查、时间一致性检查、持续性检查、背景场一致性检查、空间一致性检查、综合决策算法、自动统计评估反馈技术,并将该方案应用于2007年6-8月的实际观测资料.试验结果表明:该方案能有效地识别观测资料中存在明显错误的资料,有效地为AMDAR资料在数值模式中的应用提供客观质量依据.

In order to make use of AMDAR data better,a feasible observation data quality control module should be designed to make sure AMDAR data used in the meteorological research and operation with a higher quality.The AMDAR QC module is brought forward consulting the characteristics of AMDAR.Many quality control techniques ale integrated into the QC module,such as the station extreme value check,the interior consistency check,the consistence cheek with the first guess,the temporal consistency check,the space consistency check,the decision-making algorithm,the statistic and feedback technique.The AMDAR data quality control module has been applied into AMDAR data in August of 2007.Subjective verification result shows that error inforrnation in the observation can be distinguished effectively from the AMDAR data.
