On September 18, 2019, Prof. Dr. Daniel Rosenfeld, an internationally known atmospheric scientist, member of the European Academy of Sciences and Arts, and professor of Hebrew University of Jerusalem, along with senior engineers Dr. Yannian Zhu and Dr. Xiaohong Xu from Shaanxi Institute of Meteorological Sciences visited LIESMARS for academic exchanges on atmospheric aerosols and their climate effects.
Prof. Rosenfeld gave an academic lecture entitled "Rethinking aerosol effects on global warming" in the lecture hall on 2nd floor. He discussed his latest research on aerosol-cloud interactions, beginning with the global radiative balance and uncertainty in the IPCC report, emphasizing the important impacts of aerosols on climate change and human life, as well as the lack of awareness of aerosol climate effects. Prof. Rosenfeld introduced in detail his combined analysis of ship track distribution data, and aerosol-cloud interaction for low-level marine stratocumulus emphasizing that the previous studies based on the aerosol index underestimated radiation forcing. He argues that cloud droplet number concentration as a parameter for aerosol-cloud interaction can better characterize aerosol indirect radiative effects, and significantly reduces the uncertainty evident in previous climate change studies. During the lecture, teachers and students actively participated in the question and answer session.
After the lecture, Prof. Deren Li held an in-depth conversation with Prof. Rosenfeld on the future cooperation in the studies on active and passive remote sensing observations of clouds and aerosols, aerosol-cloud-precipitation interactions, and effects of aerosols on global climate change. This consensus will effectively promote research in the field of atmospheric aerosols and global climate change in our university.
