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 chemistry of these processes needs to be understood. And so, it is proposed to conduct a suite of novel laboratory experiments to provide a more complete view of the mechanisms of atmospheric aerosol oxidation and the potential impacts on the atmosphere.

尽管大气颗粒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表征并未得到很好的特征。特别是，一旦形成颗粒，它们就会受到可能改变其组成和化学特性的大气氧化过程。要将气候和空气质量模型置于牢固的基础上，需要了解这些过程的化学反应。因此，建议进行一套新型实验室实验，以更完整地了解大气气溶胶氧化的机理以及对大气的潜在影响。
