Evaluation of Contrail Reduction Strategies Based on Aircraft Flight Distances [PDF]
, 2012 This paper evaluates a set of contrail reduction strategies based on the flight range of aircraft as contrail reduction strategies have different impacts on aircraft depending on how they plan to fly.

Quarterly Journal of the Royal Meteorological Society, Volume 151, Issue 770, July 2025 Part A.Develop data assimilation (DA)–forecast system: a system was developed to assimilate surface CO2 concentrations to improve atmospheric CO2 concentration simulations in East Asia. Conduct observing system simulation experiments (OSSEs) and verify stability: OSSEs conducted for January and July 2019 showed that DA reduced the bias and root‐mean‐squared ...

Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.Abstract The 15 January 2022 eruption of the Hunga volcano generated a Lamb wave, a global atmospheric pressure perturbation which propagates purely horizontally at the speed of sound. Far‐field observations of the daytime passage of the Lamb wave by the Geostationary Operational Environmental Satellite‐R (GOES‐R) series, revealed unexpected ...

Few-Shot Contrail Segmentation in Remote Sensing Imagery With Loss Function in Hough Space
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingCondensation trails, or contrails, are line-shaped clouds that are produced by an aircraft engine exhaust. These contrails often impact climate significantly due to their potential warming effect.

Zero-dimensional contrail models could underpredict lifetime optical depth [PDF]
Atmospheric Chemistry and PhysicsProposed contrail avoidance schemes rely on being able to robustly predict which contrails cause the most climate warming. However, it has not yet been shown that different contrail models agree sufficiently to support the targeting of individual ...

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 12, 28 June 2025.Abstract The radiative forcing caused by contrail cirrus is nonlinearly influenced by the number of ice crystals formed in the exhaust plume behind an aircraft engine. This ice crystal number strongly depends on the properties (number, size, and solubility) of condensation nuclei in the plume available for droplet activation with subsequent freezing ...

Contrail properties over the eastern North Pacific from AVHRR data
Meteorologische Zeitschrift, 2005 An increase of air traffic over the North Pacific during the last 30 years has been accompanied by an increase in cirrus coverage. To help alleviate the uncertainty in the contribution of air traffic to the cirrus increase, an analysis of linear contrail

Estimating Contrail Climate Effects from Satellite Data [PDF]
, 2011 An automated contrail detection algorithm (CDA) is developed to exploit six of the infrared channels on the 1-km MODerate-resolution Imaging Spectroradiometer (MODIS) on the Terra and Aqua satellites.

The impact of diurnal variations of air traffic on contrail radiative forcing [PDF]
, 2007 We combined high resolution aircraft flight data from the EU Fifth Framework Programme project AERO2k with analysis data from the ECMWF's integrated forecast system to calculate diurnally resolved 3-D contrail cover.
