| 英文简介 | Dust-cloud interactions play an important role in the study of global climate change. The Northwest China is a natural laboratory to study the interactions between clouds and dust aerosols with abundant dust aerosols and lack of precipitation. In this project, a special integrated observation will be firstly designed for the study of dust-cloud interactions by employing active and passive instruments, such as cloud Radar, Multi-wavelength polarization Raman Lidar and Microwave Radiometer. Secondly, a long-term synthesized field experiment will be performed at the Semi-Arid Climate and Environment Observatory of Lanzhou University (SACOL), establishing a combined dataset including temperature and humidity vertical profiles and aerosol and cloud properties. Thirdly, a new algorithm to retrieve vertical distribution of dust aerosol microphysical properties using Raman Lidar measurements will be developed. Finally, a combination of vertical distributions of cloud and aerosol properties and the knowledge of cloud dynamic and microphysical process will help us to reveal the mechanism of dust-cloud interactions in this region. This project will facilitate the understanding of the role of dust aerosol in cloud development and provide valuable datasets and theoretical fundament for evaluating dust aerosol indirect effect, semi-direct and its impact on climate in further studies. |
