Although only microscopic in size, atmospheric particles can play an important role in Earth's climate by scattering and absorbing solar radiation and by acting as seeds for clouds. These particles can also provide a medium for chemistry. Examples of atmospheric particles include soot, mineral dust, and organic particles. Our research will focus on the reactivity and physical properties of atmospheric aerosol particles. A better understanding of the reactivity of particles and their physical properties should lead to better predictions of climate and atmospheric chemistry, including O3 chemistry.

虽然只有微观的大小，大气颗粒可以发挥重要作用，在地球的气候散射和吸收太阳辐射，并作为云的种子。这些颗粒也可以提供化学介质。大气颗粒的实例包括烟灰、矿物粉尘和有机颗粒。我们的研究将集中在大气气溶胶粒子的反应性和物理特性。更好地了解粒子的反应性及其物理特性，应该可以更好地预测气候和大气化学，包括O3化学。
