Title: Breaking the deadlocks in remote sensing for improved understanding of cloud processes and aerosol properties


Improved understanding of interactions between clouds, aerosols and precipitation is crucial for us to better determine Earth radiation and hydrological budgets, and to reduce the uncertainty in climate change predictions. Such understanding relies on their joint observation at appropriate temporal and spatial scale. In the past, it has been difficult to separate cloud droplets and raindrop embryos simultaneously in radar observations. It is also considered impossible to retrieve aerosol properties for areas strongly influenced by three-dimensional cloud radiative effects from passive satellite observations. In this talk, I will explain how we break those deadlocks. Specifically, I will show concurrent cloud and drizzle properties, and the predicted collision-coalescence process rates from our machine learning model. I will also introduce intriguing results for aerosol properties near clouds as well as in-clouds. These new retrievals will greatly enhance current observations and open many opportunities for aerosol and cloud research



Christine Chiu is an Associate Professor at the Department of Atmospheric Science, Colorado State University.  Prior to joining CSU, she was an Associate Professor at the Department of Meteorology, University of Reading, United Kingdom, a Research Assistant Professor at the University of Maryland–Baltimore County, and an Associated Scientist at NASA Goddard Space Flight Center.  Christine’s research has been largely focused on cloud and precipitation remote sensing.  She has also been working on aerosol-cloud-precipitation interactions, aerosol retrieval, and machine learning applications in radiative transfer.  Christine is currently serving as the Chair of the Cloud and Precipitation Measurements and Science Group for the Atmospheric Radiation Measurement (ARM) Climate Research Facility, and a member of the International Radiation Commission and the Hyperspectral Imaging and Sounding of the Environment Program Committee.  In the past, she has served as the Chair of the AMS Atmospheric Radiation Committee, a member of the User Executive Committee and the Science Board of ARM.
