A Review of Some Experimental Spray Methods for Marine Cloud Brightening ()

International Journal of Geosciences, 2013
Marine Cloud Brightening (MCB), should it ever need to be deployed, envisions the formation of 1017salt Cloud Condensation Nuclei (CCN) per second coming from each of several thousand vessels deployed worldwide. The creation of this many nuclei on such a vast scale, from micron- or submicron-sized seawater droplets, preferably mono-disperse, poses a ...

Measurement of a World-Wide Transfer Function for Marine Cloud Brightening

Austin Environmental Sciences, 2021
Marine cloud brightening with a sub-micron spray of filtered sea water can exploit the Twomey effect to enhance planetary cooling. Several previous climate model results show that it can also affect precipitation in both directions in different places.

Africa's Climate Response to Marine Cloud Brightening

Climate intervention through solar radiation modification is one proposed method for reducing climate risks from anthropogenic warming. Marine Cloud Brightening (MCB), one such approach, proposes to inject sea salt aerosol into a regional marine boundary layer to increase marine clouds' reflectivity.

Sensitivities of Marine Cloud Brightening Studied with a Lagrangian Cloud Model

Marine cloud brightening (MCB) is a proposed climate engineering technique in which shallow liquid clouds are deliberately seeded with aerosol particles to increase their albedo and lifetime. Development of accurate models is essential to assess the feasibility of MCB; however, this is complicated by the large number of interacting microphysical ...

The Impact of Aerosol Size on the Efficacy of Marine Cloud Brightening

The injection of sea salt produces a wide range of cloud microphysical and radiative responses in simulations of subtropical Marine Cloud Brightening (MCB) in the global climate models CESM2, E3SMv2, and CanAM5.1-PAM. Comparisons with an adiabatic cloud parcel model show that differences in the simulated cloud droplet number can be attributed to ...

Forcing Susceptibility and Climate Sensitivity to Midlatitude Marine Cloud Brightening

Journal of Climate
Abstract The climate intervention approach marine cloud brightening (MCB) would aim to reduce climate warming by injecting sea salt aerosol (iSSA) into the lower troposphere to increase cloud albedo, reflect more sunlight, and cool the surface. Due to the short atmospheric lifetime of tropospheric aerosol, MCB iSSA emissions and their

Comparison of marine cloud brightening in large eddy simulations

Modelling of marine cloud brightening (MCB), a form of solar radiation modification, has thus far proven challenging due to the incongruous nature of the scales required. The microphysics of the cloud droplets and aerosols can only be resolved at really small scales, but just as important are the large-scale impacts on circulation and radiation.
