Influence of vertical transport on free tropospheric aerosols over the central USA in springtime [PDF]
, 1998 Measurements of the atmospheric aerosol chemical composition during the Subsonic Aircraft: Contrail and Cloud Effects Special Study (SUCCESS) indicate substantial vertical transport of boundary layer aerosol to the free troposphere over the south-central

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 ...

Simulation of a contrail formation and early life cycle for a realistic airliner geometry [PDF]
Atmospheric Chemistry and PhysicsContrails – ice clouds forming in aircraft wakes – may have a radiative impact up to twice that of CO2 emissions from aviation, though significant uncertainties remain.

Contrail life cycle and properties from 1 year of MSG/SEVIRI rapid-scan images [PDF]
Atmospheric Chemistry and Physics, 2015 The automatic contrail tracking algorithm (ACTA) – developed to automatically follow contrails as they age, drift and spread – enables the study of a large number of contrails and the evolution of contrail properties with time. In this paper we present a

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.

Contrails of Small and Very Large Optical Depth [PDF]
, 2010 This work deals with two kinds of contrails. The first comprises a large number of optically thin contrails near the tropopause. They are mapped geographically using a lidar to obtain their height and a camera to obtain azimuth and elevation.

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 ...

Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.Abstract Altitude profiles of the mass concentrations of aerosol black carbon (BC) have been obtained,up to an altitude of 12 km, from in situ measurements over Hyderabad (17.47°N, 78.57°E, 557 m amsl;a tropical station in the central Indian peninsula), using three successive high altitude balloon ascents during winter and early summer seasons of 2023 ...

A 424 and 448 GHz Receiver for Aircraft Contrail Observations
IEEE Journal of MicrowavesAirplane produced contrail cirrus has a greenhouse effect in our atmosphere. It has an effect that is as much as or more than any other airplane emission such as airplane produced CO2 Karcher et al. 2018. With air traffic anticipated to increase into the
