HAQAST is a collaborative team  that works in partnership with public health and air quality agencies across the globe to use NASA data and tools for the public benefit. We are of 15 primary investigators and scores of co-investigators from across the US headquartered at the University of Wisconsin-Madison. Here you can learn about our team, publications, and newsworthy achievements. You can also find short tutorials for NASA’s open-access satellite tools.
