The “Silver Lining Project” Marine Cloud Brightening Boats

Double duty geoengineering and weather modification boats that spray oceanic salt water into clouds (marine strato-cumulus) to make them reflect sunlight (albedo modification, solar radiation management) and weaken or steer hurricanes:

The Marine Cloud Brightening Project is an open, international collaboration of atmospheric scientists and other experts to advance understanding of cloud responses to aerosol particles – a critical part of understanding the climate, and a critical area in which human activities are thought to cause significant effects.

We seek to advance scientific understanding in this area by developing a framework and associated technology that will allow the scientific community to conduct experiments to understand cloud processes with a much greater degree of control than has previously been possible.

To do this we propose to:

1. Develop new models and improve existing models of aerosol-cloud interactions needed for accurate modeling of climate and climate change.
2. Use advanced techniques such as machine learning to analyze cloud-aerosol data to test and inform models.
3. Develop spray technology that will generate controlled volumes and sizes of tiny sub-micrometer seawater particles in sufficient numbers to increase the local brightness of low clouds in a marine environment.
4. Conduct small-scale, controlled field experiments with to provide new understanding of the interactions between aerosols and clouds. [1]

This research is currently undertaken by distinguished scientists and engineers at: Manchester University, Leeds University, NCAR, Pacific Northwest National Labs, Purdue University, University of Washington and the University of Edinburgh. [2]

“cool ocean surface waters in the regions in which the genesis of hurricanes occurs. This would be achieved by seeding low-level maritime stratocumulus clouds covering these regions – or ones from which ocean currents flow into these regions – in order to increase their reflectivity for incoming sunlight: thus producing a cooling.” [3]
