本文主要关注的研究集中在但不限于海洋云增亮（MCB）方面，海洋云增亮是减少到达地球表面的阳光量的几种地球工程思想之一，从而补偿化石燃料燃烧造成的全球变暖。主要的注意力放在发展产生亚微米盐粒子喷雾的技术上，这些盐粒子可以进入海洋层积云并增加其扩散，从而产生冷却。描述了通过在超临界条件下喷射盐溶液来产生亚微米盐颗粒，沿着描述了所使用的装置。通过该技术的两种变化产生具有32至286 nm的中值直径的对数正态粒度分布，其中GSD（几何标准差）约为2。(C)2013爱思唯尔有限公司版权所有。
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 global warming resulting from fossil-fuel burning. Predominant attention is given to the development of techniques for generating sprays of sub-micrometer salt particles that can enter marine stratocumulus clouds and increase their albedo, thus producing a cooling. Generation of sub-micrometer salt particles by spraying salt solutions at supercritical conditions is described, along with a description of the apparatus used. Log-normal particle size distributions having median diameters of 32 to 286 nm, with GSDs (Geometric Standard Deviations) around 2, were generated by two variations on the technique.
