Megaplume of Saharan desert dust travels all the way to Scandinavia. NASA satellite tracked its progress.

Megaplume of Saharan desert dust travels all the way to Scandinavia. NASA satellite tracked its progress.

Atmospheric scientists track aerosols—tiny solid and liquid particles suspended in our atmosphere —because they have important impacts on weather, climate, and human health. Mineral dust is one of the most abundant aerosols, a product of winds blowing across our deserts and beaches, picking up tiny bits of rock and sand and distributing them all over the world. Dust can fertilize the ocean for plankton and seed the sky for cloud formation. Sometimes dust storms are just cool to watch, as well. In this series of images from the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite, the dust from a Saharan sand storm blows several thousand kilometers over the North Atlantic and Europe in April 2011. Aerosol concentrations in the air are represented by a quantity known as the aerosol index, with the highest concentrations in deep red and the lowest in light yellow. The g...
