Evaluation of Pulse Aerosol Forcing on Marine Stratocumulus Clouds in the Context of Marine Cloud Brightening

Journal of the Atmospheric Sciences, 2023
Abstract We explore the effect of aerosol perturbations on stratocumulus clouds in the context of marine cloud brightening (MCB) using high-resolution large-eddy simulations. We use a Lagrangian cloud microphysical model with a very detailed treatment of aerosol activation and droplet growth.

Note for COP26 on Marine Cloud Brightening

Austin Environmental Sciences, 2021
Present policies of most Governments, with a few predictable exceptions, concentrate on the desperate need to get to zero carbon emissions as soon as possible. This is a necessary but not sufficient objective. There is strong evidence from the Keeling curve in figure 1, about the difficulty (Figure 1).

Sub-micrometer salt aerosol production intended for marine cloud brightening

Atmospheric Research, 2014
This paper is largely concerned with research focused on, but not restricted to, aspects of Marine Cloud Brightening (MCB), one of several geo-engineering ideas for reducing the amount of sunlight arriving at the Earth's surface, thereby compensating for

The inclusion of water with the injected aerosol reduces the simulated effectiveness of marine cloud brightening [PDF]

Atmospheric Science Letters, 2013
Sea-salt aerosols proposed for injection in marine cloud brightening geoengineering would likely result from evaporation of sea-water droplets. Previous simulations have omitted this mechanism.

Sub-micrometer salt aerosol production: Marine Cloud Brightening

2013 IEEE Global Humanitarian Technology Conference (GHTC), 2013
We review in some detail research into experimental spray methods for the production of salt nanoparticles from seawater, which would be needed for the implementation of Marine Cloud Brightening (MCB), a possible climate change mitigation method. We describe first an electrospray method employing Taylor cones spraying seawater, which fortuitously has ...

Impact of Seasonality on Climate Outcomes for Mid Latitude Marine Cloud Brightening

Geophysical Research Letters
Most previous studies on marine cloud brightening (MCB) have focused on deployment over the subtropical stratocumulus cloud decks which persistently result in non-uniform cooling and disruption of the El Nino Southern Oscillation (ENSO). A recent study demonstrated that MCB deployment over mid-latitudes, instead, could alleviate such side effects. Here,

Cloud Microphysical Implications for Marine Cloud Brightening: The Importance of the Seeded Particle Size Distribution

Journal of the Atmospheric Sciences, 2021
AbstractMarine cloud brightening (MCB) has been proposed as a viable way to counteract global warming by artificially increasing the albedo and lifetime of clouds via deliberate seeding of aerosol particles. Stratocumulus decks, which cover wide swaths of Earth’s surface, are considered the primary target for this geoengineering approach.

IMPACTS OF MARINE CLOUD BRIGHTENING ON MAJOR METROPOLISES IN THE ARID ARAB REGION

International Journal of Big Data Mining for Global Warming, 2023
Climatic extreme events will occur more frequently, which will seriously threaten the life safety of residents in arid and semi-arid areas. Cairo, Algiers and Dubai are located at the crossroads of the global climate pattern. Climatic extreme events will seriously threaten the lives of local residents.

A Parameterization of Interstitial Aerosol Extinction and Its Application to Marine Cloud Brightening

Journal of the Atmospheric Sciences, 2022
Abstract Marine cloud brightening (MCB) is a geoengineering approach to counteract climate change by the deliberate seeding of sea salt aerosol particles that, once they activated to cloud droplets, directly increase cloud reflectance and hence global albedo.
