Every cloud drop is formed from a microscopic aerosol particle, known as a cloud condensation nuclei (CCN). In unpolluted environments the CCN particles originate from biogenic sources. Determining the magnitude and driving factors of biogenic aerosol production in different ecosystems is crucial to the development and improvement of climate models. This project aims to determine the mechanisms of new particle production from one of the biggest ecosystems in Australia, the Great Barrier Reef. It is expected that the project will establish whether marine aerosol along the Queensland coast is coral-derived and show that this aerosol can affect the CCN concentration and therefore cloud formation and the hydrological cycle.

每一个云滴都是由一个微观的气溶胶粒子形成的，称为云凝结核（CCN）。在未受污染的环境中，CCN颗粒来自生物源。确定不同生态系统中生物气溶胶产生的大小和驱动因子对于发展和改进气候模式至关重要。该项目旨在确定澳大利亚最大的生态系统之一大堡礁产生新颗粒的机制。预计该项目将确定昆士兰州海岸沿着的海洋气溶胶是否源自珊瑚，并表明这种气溶胶可以影响云凝结核浓度，从而影响云的形成和水文循环。
