Tiny particles in the atmosphere and human-caused enhancements of those fine particles contribute to poor air quality in the Southeastern U.S. The summer Southeast Nexus (SENEX) study helped scientists determine the origin of these fine particles and how they contribute to the haziness in the region and affect regional air quality and temperature trends. More on investigating Southeast air quality and climate mysteries.
