探空温度偏差订正技术调研报告
Research Report on Radiosonde Temperature Bias Correction
中文摘要：
探空资料在数值预报、资料同化、天气分析、气候变化、卫星资料校准等研究中发挥着重要作用。探空温度偏差大小持续受到太阳辐射等自然因素、观测系统改变等历史人为因素的叠加耦合作用影响，使得其偏差订正工作变得非常复杂，给上述众多研究应用带来较大的困扰和不确定性。本文调研了国内外主要探空温度偏差订正技术和相关产品的发展现状，重点对比分析国外不同科研业务单位的技术方法，同时结合中国探空温度偏差订正技术的发展现状和国内外差距，对未来工作提出展望。

Abstract：
Sounding data play an important role in numerical prediction, data assimilation, weather analysis, climate change, satellite data calibration and other research. The magnitude of sounding temperature bias is continuously affected by natural factors such as solar radiation and historical human factors such as changes in observation system, which make the bias correction work very complex. It has brought great trouble and uncertainty to the above research fields. Based on the investigation of the development status of the main technologies and related products of the sounding temperature bias correction in demostic and overseas, this paper focuses on the comparison and analysis of the technical methods of different foreign scientific research institutions, discusses the development status of the sounding temperature bias correction in China, puts forward relevant suggestions for future research plans.
