Marine cloud brightening [PDF]

Philosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 2012
Abstract The idea behind the marine cloud-brightening (MCB) geoengineering technique is that seeding marine stratocumulus clouds with copious quantities of roughly monodisperse sub-micrometre sea water particles might significantly enhance the cloud droplet number concentration, and thereby the cloud albedo and possibly longevity ...

Effects of Sea Salt Aerosol Emissions for Marine Cloud Brightening on Atmospheric Chemistry: Implications for Radiative Forcing [PDF]

Geophysical Research Letters, 2020
Marine cloud brightening (MCB) is proposed to offset global warming by emitting sea salt aerosols to the tropical marine boundary layer, which increases aerosol and cloud albedo. Sea salt aerosol is the main source of tropospheric reactive chlorine (Cly)

Factors determining the most efficient spray distribution for marine cloud brightening [PDF]

Philosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 2014
We investigate the sensitivity of marine cloud brightening to the properties of the added salt particle distribution using a cloud parcel model, with an aim to address the question of, ‘what is the most efficient particle size distribution that will produce a desired cooling effect?’ We examine the effect that altering the aerosol particle

Marine Cloud Brightening to Cool the Arctic: An Earth System Model Comparison

Earth's Future
Marine cloud brightening (MCB) via sea‐salt aerosol (SSA) injections is one commonly researched method to cool the Earth either regionally or globally, and potentially reduce impacts of global warming.

Natural marine cloud brightening in the Southern Ocean [PDF]

Atmospheric Chemistry and Physics, 2023
The number of cloud droplets per unit volume (Nd) is a fundamentally important property of marine boundary layer (MBL) liquid clouds that, at constant liquid water path, exerts considerable controls on albedo.

Marine cloud brightening: regional applications. [PDF]

Philos Trans A Math Phys Eng Sci, 2014
The general principle behind the marine cloud brightening (MCB) climate engineering technique is that seeding marine stratocumulus clouds with substantial concentrations of roughly monodisperse sub-micrometre-sized seawater particles might significantly enhance cloud albedo and longevity, thereby producing a cooling effect. This paper is concerned with

Subtropical Marine Cloud Brightening Suppresses the El Niño–Southern Oscillation

Earth's Future
Stratospheric aerosol injection (SAI) and marine cloud brightening (MCB) are two proposed methods of compensating for greenhouse gas‐induced warming by reflecting incoming solar radiation. However, their effects on the El Niño–Southern Oscillation (ENSO),
