Our ability to understand and predict climate change is limited due to uncertainties in how humans have modified aerosols (atmospheric particles) and clouds. This is the most uncertain factor in recent climate change quantified by the Intergovernmental Panel on Climate Change. This uncertainty is both from the impact that aerosols have on clouds and the impact of clouds on aerosol size, concentration and chemical composition. In this research program, we will investigate the interactions of aerosols and clouds while paying specific attention to the impact of these interactions on climate.

由于人类如何改变气溶胶（大气颗粒）和云的不确定性，我们理解和预测气候变化的能力有限。 这是政府间气候变化专门委员会量化的最近气候变化中最不确定的因素。 这种不确定性既来自气溶胶对云的影响，也来自云对气溶胶大小、浓度和化学成分的影响。在这项研究计划中，我们将调查气溶胶和云的相互作用，同时特别注意这些相互作用对气候的影响。
