A thick plume of haze blew off the coast of China, across the Yellow Sea, and toward the Korean Peninsula in early December 2008. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite took this picture on December 2, 2008. In this image, the gray haze is thick enough to obscure the satellite’s view of the South Korean coast. The haze appears thickest over South Korea and thins toward the north. Over North Korea, skies are largely clear. The haze likely results from a combination of agricultural fires and industrial and urban pollution.
On February 6, 2007, thick haze blew across the Yellow Sea and the Korean Peninsula toward Japan. In this image, the band of haze appears to narrow somewhat as it crosses over South Korea, then spreads out over the Sea of Japan (East Sea).
