对飞机尾迹辐射强迫进行了全球计算。使用了基于航空燃料消耗和太阳和热红外辐射的辐射传输模型计算的尾迹分布。与以前的研究相比，由于尾迹（约0.01 Wm−2）的净辐射强迫估计小得多，强调了这个值的强烈敏感性的不确定性，在长波和短波的贡献。太阳强迫是负的，并且在太阳天顶角高的时候强度最大。改变飞机飞行的时间有可能减少由于尾迹引起的辐射强迫，并且在本文给出的某些假设下，净零强迫。
Global calculations of the radiative forcing due to contrails from aircraft are performed. A contrail distribution computed based on aviation fuel consumption and radiative transfer models for solar and thermal infrared radiation have been used. A substantially smaller net radiative forcing due to contrails (about 0.01 Wm−2) is estimated in comparison to former studies, emphasizing the strong sensitivity of this value to uncertainties in the longwave and shortwave contribution. The solar forcing is negative and the magnitude maximizes for high solar zenith angles. Altering the time for aircraft traffic has the potential for reducing the radiative forcing due to contrails, and under certain assumptions made in this paper giving a net zero forcing.
