Dust concentration in the air

Each map represents the amount of dust in the air that was recorded that year. The amount of dust in the air has been calculated as Dust Concentration (µg/m3).
µg/m3 = micrograms per cubic metre. 1µg = 1 millionth of a gram. For more information on the data displayed in these maps,contact us. You can also read about Dust Concentration data in the Wind Erosion Histories.
