The Conference on Molecular-Level Understanding of Atmospheric Aerosols (MUOAA 2020); Lake Arrowhead, California; September 20-25, 2020

该讲习班汇集了在实验室和实地基础上研究大气气溶胶的科学家。这次会议的目的是提供气溶胶特性的分子水平的观点，这些特性对气溶胶对空气质量、气候、环境和人类健康的影响至关重要。会议的重点将是对解释和预测短期和长期气候所需的大气过程的基本理解，以及对影响这些过程的关键因素大气气溶胶的理解。本次研讨会的学术价值包括讨论在理解气溶胶粒子从气态前体形成和这些粒子的初始生长、气溶胶的内部结构、气溶胶相行为、异质和多相（光）化学、气体-表面相互作用、气溶胶引发冰和云成核的能力、气溶胶光学特性的演变、以及生物气溶胶在大气中的作用。研讨会将于2020年9月在UCLA Lake Arrowhead会议中心举行。 NSF对本次会议的支持将用于学生、博士后和早期职业专业人士的旅行。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This workshop brings together scientists involved in studying atmospheric aerosols at a fundamental level in the laboratory and in the field. The objective of the gathering is to provide molecular level perspectives on aerosol properties that are critical to the impact of aerosols on air quality, climate, and environmental and human health.The focus will be on the fundamental understanding of atmospheric processes that is needed to interpret and predict climate at both short and long time scales, and on the atmospheric aerosols that are key players that influence these processes. The intellectual merit of this workshop includes the discussion of challenges that exist in understanding the formation of aerosol particles from gaseous precursors and the initial growth of these particles, the internal structure of aerosols, aerosol phase behavior, heterogeneous and multiphase (photo)chemistry, gas-surface interactions, the ability of aerosols to initiate ice and cloud nucleation, the evolution of aerosol optical properties, and the role of bioaerosols in the atmosphere. The workshop will be held at the UCLA Lake Arrowhead Conference Center in September, 2020. NSF support for this meeting will go towards travel for student, postdoctoral, and early career professionals.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
