 In their Explore Series lecture, and car scientists Dr. Helen Warden and Dr. David Edwards discuss what can satellites tell us about the quality of the air we breathe? In this talk we're going to try and hit some of the topics that are of interest to people right now. The air around us is very smoky as a result of the fires, the burning on the west coast. Southpipes have this bird's-eye view of the atmosphere and give us this very large-scale perspective. We're also going to talk about how we do this, how we can sense from space the trace gases that make up pollution and why it affects our health so much. We'll also talk a little bit about the reduction in pollution that occurred during the COVID lockdown. We can measure pollution everywhere, so this really can help places maybe that don't have a lot of their own observations. We really want folks to understand the new satellites that we're working on right now will hopefully give us a really better understanding on predicting the air quality around us.
