This project aims to provide fundamental process-level understanding of atmospheric aerosol processes over the Southern Ocean, a region that has a profound influence on the Australian and global climate and where climate models perform poorly. Comprehensive observations during 3 Southern Ocean voyages and land-based measurements will enhance our knowledge of aerosols and cloud formation in that region and provide much-needed data for improving global climate models. Expected outcomes include more accurate seasonal and latitudinal representations of Southern Ocean aerosol populations, properties and sources. The main benefit includes improvements in weather forecasting and future climate projection for Australia and the Southern Hemisphere.

该项目旨在提供对南大洋大气气溶胶过程的基本过程水平的了解，南大洋对澳大利亚和全球气候具有深远影响，气候模型表现不佳。在三次南大洋航行期间进行的全面观测和陆基测量将增进我们对该区域气溶胶和云形成的了解，并为改进全球气候模型提供急需的数据。预期的成果包括更准确地说明南大洋气溶胶的数量、特性和来源的季节和纬度。主要的好处包括改善澳大利亚和南半球的天气预报和未来气候预测。
