Florida air loaded with African dust.

Researchers at the University of Miami This article is about the university in Coral Gables, Florida. For the university in Oxford, Ohio, see Miami University.

The University of Miami (also known as Miami of Florida,[2] UM,[3] or just The U
 have collected daily dust samples since 1974 from an island just off the Miami coast. Each summer, they have recorded large quantities of fine particles on days when winds carried African dust storms toward North America. The scientists can identify the source of the dust because satellite images show the progress of the storms as they cross the Atlantic. Moreover, the dust has a distinctive red-brown color, says Joseph M. Prospero.

During months when the African dust is absent, researchers measure just a few micrograms of dust per cubic meter of air. In summer, the value often surges to 50 or 100 micrograms, with the African particles accounting for most of the increase.

Current EPA regulations set standards for particles smaller than 10 micrometers in diameter, but the agency has proposed adding a different limit for particles under 2.5 micrometers. Roughly half of the African dust would meet this criterion, says Prospero. "Given the new EPA standards, it looks like Florida will be in noncompliance noncompliance

The new regulations include provisions for states to exempt times when certain natural sources--such as volcanic eruptions volcanic eruptions

 or forest fires--boost the number of particles in the air. As yet, however, they have not included African dust as one of these exemptions.
