中文摘要:喷气式飞机在对流层上层的航空活动形成的尾迹云能够影响区域气候,对全球变暖有正的贡献。飞机尾迹云的辐射强迫与飞机尾迹云的区域覆盖率,物理特性以及光学特性密切相关。本文分析总结了线状尾迹云的不同识别方法,并回顾了近几十年来线状尾迹云的相关研究进展。首先讨论了欧美主流的尾迹云检测算法(Contrail Detection Algorithm,CDA)及其延伸算法,并总结了线状尾迹云在西欧北美等地区覆盖率的季节和昼夜变化特点;接着讨论了以往多种线状尾迹云光学厚度的计算方案以及其计算不确定性;最后分析了线状尾迹云的辐射强迫与覆盖率和光学厚度的关系,并指出目前飞机尾迹云相关研究存在的问题以及未来发展方向。

Review of aircraft contrail recognition and its radiative forcing
Abstract:Jet aviation activities in the upper troposphere produce contrails, which affect the regional climate with a positive contribution to global warming. The radiative forcing is closely related to the regional coverage, physical properties and optical properties of contrails, which directly affect the climate change.In this paper, we summarize the different recognition methods of line-shaped contrails, and review the related research progress of line-shaped contrails in recent decades. Firstly, the Contrail Detection Algorithm (CDA) and its various extension algorithms are discussed in this paper, we summarize the seasonal and diurnal variation characteristics of the line-shaped contrails in Western Europe and other regions. Then we discuss several calculation schemes of optical depth of line-shaped contrails and its calculation uncertainty. Finally, we analyse that how the coverage and the optical depth of the line-shaped contrail impact the radiative forcing and point out the problems existing in present studies of the contrail and the future development direction.
