Early Warning System Helps Puerto Rico Prepare for Saharan Dust

Puerto Ricans can breathe easier thanks to the work of John Haynes, program manager of the NASA Earth Applied Sciences Health and Air Quality program area, and Pablo Méndez-Lázaro, an associate professor at the University of Puerto Rico Medical Sciences Campus in San Juan, and principal investigator for this project.
The team developed an early warning system that tracks dust via satellite and provides up to three days' notice when Saharan dust travels across the Atlantic Ocean.
This tool helps health and weather experts warn residents about the poor visibility and air quality conditions caused by Saharan dust sooner than ever before.
