Weather and climate predictions lack fundamental information to link nanoscale aerosols, which are suspended liquids or solids, to precipitation processes that would allow models to better predict rain and snowfall at local and global scales. Models for weather and climate need to incorporate microphysical and chemical details about the atmosphere, and characteristics of aerosols, that influence the initiation of precipitation. This proposal aims to bridge a gap in our knowledge of processes governing precipitation by identifying characteristics of aerosols responsible for initiating and sustaining rain and snowfall.

天气和气候预测缺乏将纳米级气溶胶（悬浮液体或固体）与降水过程联系起来的基本信息，这些信息将使模型能够更好地预测局部和全球尺度的降雨和降雪。天气和气候模型需要纳入大气的微物理和化学细节，以及影响降水开始的气溶胶特性。该提案旨在通过确定负责启动和维持降雨和降雪的气溶胶的特性，弥补我们对降水过程的认识上的差距。
