HAQAST St. Louis

The Health and Air Quality Applied Sciences Team (HAQAST)  works to connect NASA satellite data and products with public health experts and air quality managers. Our team of 14 PIs and 70+ total collaborating investigators has grown to support and serve hundreds of organizations across the U.S. and around the world. Our public meetings are opportunities to grow these two-way dialogues in which stakeholders share their research needs and priorities, and scientists share their resources, insights, and new discoveries.

This meeting was  held in-person and online November 6th – 7th, 2025 at the Knight Center at Washington University in St. Louis, kicking off the new HAQAST team. This meeting highlighted new HAQAST member projects and explored topics areas such as satellite data for different sectors including industry and education, applications for forecasting smoke and dust, regulatory compliance, and public health, across scales from local to global.
