Although atmospheric particles are of crucial importance to both human health and global climate, their detailed chemistry in the atmosphere is not well characterized. In particular, once particles are formed, they are subject to atmospheric oxidative processes that may alter their composition and chemical properties. To place climate and air quality models on a firm fundamental foundation, the physical chemistry of these processes needs to be understood. And so, it is proposed to conduct a suite of novel experiments to provide a unified view of the mechanism of atmospheric aerosol oxidation and the potential impacts on the atmosphere.

尽管大气颗粒物对人类健康和全球气候都至关重要，但它们在大气中的详细化学特征尚未得到很好的描述。特别是，一旦颗粒形成，它们就会受到大气氧化过程的影响，这可能会改变它们的组成和化学性质。要将气候和空气质量模型建立在坚实的基础上，需要了解这些过程的物理化学。因此，建议进行一系列新颖的实验，以提供对大气气溶胶氧化机理和对大气的潜在影响的统一看法。
