Modeling the Impact of Alternative Fuels and Hydrogen Propulsion on Contrail‐Cirrus: A Parameter Study

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 2, 28 January 2026.
Abstract Line‐shaped contrails formed behind aircraft can evolve into broadly spread and long‐living cirrus clouds under favorable conditions. These contrail‐cirrus contribute significantly to the aviation‐induced radiative forcing. While past modeling studies have examined contrail‐cirrus across various atmospheric and aircraft‐type dependent ...

New evidence on the relationship beetween crude oil and petroleum product prices [PDF]

open access: yes
The present study aims at providing new evidence on the price re- lationships between crude oil and petroleum products. We employ single-equation error correction models (ECM) in which both changes in crude oil price and deviations from the long-run ...
