GeoHealth Frontlines

Ep2: Seeing Air Pollution from Space

In our second episode, we welcome Professor Tracey Holloway from the University of Wisconsin–Madison, a leader in air quality science at the intersection of satellites, policy, and public health. Tune in as she shares her journey into GeoHealth, how satellite observations can help us understand air pollution at scales relevant to people and decision-makers, and lessons from leading NASA’s Health and Air Quality Applied Sciences Team (HAQAST) on translating science into real-world impact. Guest: Professor Tracey Holloway is a Professor at the University of Wisconsin–Madison. Her research advances air quality science to inform policy and public health. She has served as a two-time leader of NASA’s Health and Air Quality Applied Sciences Team (HAQAST) and has been recognized as an AGU Fellow and a member of the National Academy of Medicine.

EP1: The Dust We Breathe

We’re thrilled to introduce GeoHealth Frontlines, a new podcast from the AGU GeoHealth Section. Hosted by the AGU GeoHealth communication and outreach committee, the series spotlights conversations with scientists, policymakers, and practitioners tackling the world’s most pressing environment-health challenges. In our first episode, we welcome Professor Daniel Tong from George Mason University — an expert in air quality and emissions modeling, chair of the WMO Sand and Dust Storms Advisory System, and current President of AGU GeoHealth. Tune in as he shares his journey, insights from the UN High-Level Meeting on Dust Storms, how desert dust affects global health and policy, and how you can get involved with AGU Geohealth. Guest: Professor Daniel Tong is an associate professor at Atmospheric, Oceanic & Earth Sciences Department in George Mason University. He has over 20 years of experience in emissions and air quality modeling. Among his many positions, he is the Chair of World Meteorological Organization (WMO) Sand and Dust Storms Warning Advisory & Assessment System, and the current president of AGU Geohealth.
