Occurrence of lower cloud albedo in ship tracks [PDF]

Atmospheric Chemistry and Physics, 2012
The concept of geoengineering by marine cloud brightening is based on seeding marine stratocumulus clouds with sub-micrometer sea-salt particles to enhance the cloud droplet number concentration and cloud albedo, thereby producing a climate cooling ...

Impacts of three types of solar geoengineering on the Atlantic Meridional Overturning Circulation [PDF]

Atmospheric Chemistry and Physics, 2022
Climate models simulate lower rates of North Atlantic heat transport under greenhouse gas climates than at present due to a reduction in the strength of the Atlantic Meridional Overturning Circulation (AMOC).

Solar Geoengineering in the Polar Regions: A Review

Earth's Future, 2023
Solar geoengineering refers to proposals, including stratospheric aerosol injection (SAI), to slow or reverse climate change by reflecting away incoming sunlight.

Assessing the potential efficacy of marine cloud brightening for cooling Earth using a simple heuristic model [PDF]

Atmospheric Chemistry and Physics, 2021
A simple heuristic model is described to assess the potential for increasing solar reflection by augmenting the aerosol population below marine low clouds, which nominally leads to increased cloud droplet concentration and albedo. The model estimates the

Ice nuclei in marine air: biogenic particles or dust? [PDF]

Atmospheric Chemistry and Physics, 2013
Ice nuclei impact clouds, but their sources and distribution in the atmosphere are still not well known. Particularly little attention has been paid to IN sources in marine environments, although evidence from field studies suggests that IN ...

The climate effects of increasing ocean albedo: an idealized representation of solar geoengineering [PDF]

Atmospheric Chemistry and Physics, 2018
Geoengineering, or climate intervention, describes methods of deliberately altering the climate system to offset anthropogenic climate change. As an idealized representation of near-surface solar geoengineering over the ocean, such as marine cloud ...

Toward data assimilation of ship-induced aerosol–cloud interactions

Environmental Data Science, 2022
Satellite imagery can detect temporary cloud trails or ship tracks formed from aerosols emitted from large ships traversing our oceans, a phenomenon that global climate models cannot directly reproduce. Ship tracks are observable examples of marine cloud

Substantial Diel Changes of Cloud Adjustments to Aerosols in Ship‐Tracks

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Clouds adjust their albedo, amount and liquid water path to anthropogenic aerosols, and produce a climate forcing. Such cloud adjustments are complex functions of both environmental conditions and interaction time. However, direct observations of temporal changes in cloud adjustments are limited. Here, we develop a method to show observational
