海洋云增亮(MCB)是将气溶胶粒子注入浅层海洋云，以增加其对太阳辐射的反射，并减少气候系统吸收的能量。
研究人员称，从物理科学的角度来看，一个广泛的国际科学家团体的共识是，MCB的可行性最终将取决于观测和模式是否能够，有效地评估当今气候从局部到全球变亮的规模并确定策略，确保与预估的区域温度和降水变化相关的利益和风险在地理上的公平分配。
为了解决评估MCB的社会影响所需的物理科学知识缺口，该研究团队提出了一个实质性的、有针对性的研究计划，即现场和实验室实验、监测和数值模拟项目。

Abstract: Marine cloud brightening (MCB) is the deliberate injection of aerosol particles into shallow marine clouds to increase their reflection of solar radiation and reduce the amount of energy absorbed by the climate system. From the physical science perspective, the consensus of a broad international group of scientists is that the viability of MCB will ultimately depend on whether observations and models can robustly assess the scale-up of local-to-global brightening in today’s climate and identify strategies that will ensure an equitable geographical distribution of the benefits and risks associated with projected regional changes in temperature and precipitation. To address the physical science knowledge gaps required to assess the societal implications of MCB, we propose a substantial and targeted program of research—field and laboratory experiments, monitoring, and numerical modeling across a range of scales.
