Pringle, K. J.; Carslaw, K. S.; et al. (2012): A multi-model assessment of the efficacy of sea spray geoengineering

Pringle, K. J.; Carslaw, K. S.; Fan, T.; Mann, G.W; Hill, A.; Stier, P. et al. (2012): A multi-model assessment of the efficacy of sea spray geoengineering. In: Atmos. Chem. Phys. Discuss 12 (3), pp 7125–7166.

"Artificially increasing the albedo of marine clouds by the mechanical emission of sea spray aerosol has been proposed as a geoengineering technique to slow the warming caused by anthropogenic greenhouse gases. A previous global model study found that only modest increases and sometimes even decreases in cloud drop number (CDN) concentrations would result from plausible emission scenarios. Here we extend that work to examine the conditions under which decreases in CDN can occur, and use three independent global models to quantify maximum achievable CDN changes."
