Zheng Liu

Zheng is a Research Scientist who joined the Polar Science Center as a post-doctoral research associate in 2013. He received his PhD in Atmospheric Sciences at the University of Washington in 2012, supervised by Dr. Thomas Ackerman. His PhD work focused on the analysis of observations of high-level clouds in the tropics and the mid-latitudes, and the evaluation of their representation in cloud resolving model. His current work focuses on the interactions between cloud and sea ice through various processes, using an atmospheric regional model (Polar WRF) and a cloud resolving model (System for Atmospheric Modeling).

Zheng has participated in several aerial surveys of the seasonal ice zones in the Beaufort and Chukchi seas,  such as the Seasonal Ice Zone Reconnaissance Survey on the US Coast Guard C-130 (since 2014) and the NOAA Arctic Heat campaign (2020). The observations from dropsondes and a new imaging system (LATIS), including IR/visible cameras, IR radiometer, and lidar provide a unique opportunity to investigate the interactions among ocean, sea ice, and atmosphere in the seasonal ice zone in high spatial and temporal resolutions.
