Dust obscuring most of the Liaoning region of China and parts of northern and western Korea. Left: March 23, 2002, a relatively clear day. Right: April 8, 2002, a day of extremely dusty skies. Storms transport mineral dust from the deserts of China and Mongolia over great distances, as well as pollution from agriculture, industry and power generation. Asian dust has been detected as far away as Colorado. Thick clouds of dust block substantial amounts of incoming sunlight, which in turn can influence marine phytoplankton production and have a cooling effect on regional climates.
