    On October 20, 2022, the Moderate Resolution Imaging Spectroradiometer
    (MODIS) on board NASA’s Aqua satellite acquired a true-color image of a
    long plume of dust blowing across Afghanistan and Turkmenistan. The
    dust appears to rise from a wide source near the border of Afghanistan
    and Uzbekistan, then is swept westward by strong winds. The plume of
    dust is so thick that not only does it obscure the land beneath, but
    the airborne dust forms dune-like waves which creates a textured
    appearance.

    The region’s dry terrain is a mixture of rugged mountains and sandy or
    rocky deserts. Dust storms can happen any time of the year in
    Afghanistan. On average, Afghanistan experiences blowing dust one to
    two days per month in the winter and six days per month at the height
    of the summer.
