It is the purpose of this investigation to study the physics and chemistry of very small atmospheric particles called Aitken particles. The study has three parts: 1) to develop a climatology of aerosols, that is to determine how the aerosol size distribution and number concentration varies with the origin of the air mass being studied; 2) to attempt to confirm the essential features of a model developed by the proposer called "The Cloud Erosion Model". This model predicts very definite changes in the size distribution and number concentration of aerosol as a function of the history of the airmass; 3) to study the possible production of aerosols by photochemistry in the clean arctic air.

本研究的目的是研究物理学， 一种叫做艾特肯的非常小的大气颗粒的化学 粒子 研究报告分为三个部分： 1)发展气溶胶的气候学， 气溶胶的大小分布和数量浓度 随所研究的气团来源而变化; 2)试图确认一个模型的基本特征 被称为“云侵蚀模型”。 这个模型预测了非常明确的大小变化， 气溶胶的分布和数浓度， 气团历史的作用; 3)研究可能产生的气溶胶， 北极清洁空气中的光化学
