Simulated radiative forcing from contrails and contrail cirrus
Listed in National Center for Atmospheric Research
A comprehensive general circulation model including ice supersaturation is used to estimate the climate impact of aviation induced contrails.
Description
The model uses a realistic aviation emissions inventory for 2006 to initiate contrails, and allows them to evolve consistently with the model hydrologic cycle. The radiative forcing from linear contrails is very sensitive to the diurnal cycle.
For linear contrails, including the diurnal cycle of air traffic reduces the estimated radiative forcing by 29%, and for contrail cirrus estimates, the radiative forcing is reduced by 25%. Estimated global radiative forcing from linear contrails is 0.0031 ± 0.0005 Wmâ»Â². The linear contrail radiative forcing is found to exhibit a strong diurnal cycle.

The contrail cirrus radiative forcing is less sensitive to the diurnal cycle of flights. The estimated global radiative forcing from contrail cirrus is 0.013 ± 0.01 Wmâ»Â². Over regions with the highest air traffic, the regional effect can be as large as 1 Wmâ»Â².
