On the Timescales of Atmospheric Adjustments to Contrail Cirrus Formation

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Condensation trails (contrails) that evolve into contrail cirrus may constitute the largest contribution to aviation's climate impact. However the strength and timescales of the adjustments of the upper atmospheric water budget to contrail formation are poorly known. Thanks to multiple simulations with the ICOLMDZ climate model, the relatively
