The magic of minerals in the air.
Atmospheric dust refers to the mixture of particles in the atmosphere, which originate from the world´s deserts.
These particles are suspended in the atmosphere, varying in size, composition and source. The particles can be removed from the atmosphere by wet and dry deposition and fall back on soil, vegetation or bodies of water. The winds help them travel through the air.
Where does atmospheric dust come from?
We're going on a trip around the world...
Mainly from deserts! Starting from here, these mineral dust particles are lifted by winds which sweep them the into our atmosphere. It then starts travelling from the arid and dry regions in the Dust Belt in the Northern Hemisphere and can reach places as far as the Caribbean, or the Amazon basin.
How cool does that sound?
How does it travel?
Megatons per year
or more can be lifted from the deserts and enter the atmosphere
of aerosols in the atmosphere are dust particles lifted by wind
is the distance particles can travel from the Sahara to the Caribbean or Amazon
