Description The desert takes to the skies in these images of eastern China from NASA's Multi-angle Imaging SpectroRadiometer (MISR). A hazy summer view from July 9, 2000, (left) compares with a spectacularly dusty spring view from April 7, 2001, (middle). The two images cover an area from central Manchuria near the top to portions of North and South Korea at the bottom. The image on the right is a higher resolution MISR nadir- camera view of a portion of the April 7, 2001, dust cloud. When viewed at full magnification, a number of atmospheric wave features, like the ridges and valleys of a fingerprint, are apparent. These are probably induced by surface topography, which can disturb the wind flow. A few small cumulus clouds are also visible and are casting shadows on the thick lower dust layer. According to the Xinhua News Agency in China, nearly one million tons of Gobi Desert dust blow into Beijing each year. During a similar dust outbreak last year, the Associated Press reported that the visibility in Beijing had been reduced to the point where buildings were barely visible across city streets and airline schedules were significantly disrupted. The dust has also been implicated in adverse health effects such as respiratory discomfort and eye irritation. Asia's desert areas are prone to soil erosion, as underground water tables are lowered by prolonged drought and by industrial and agricultural water use. Heavy winds blowing eastward across the arid and sparsely vegetated surfaces of Mongolia and western China pick up large quantities of yellow dust. Airborne dust clouds from the April 2001 storm blew across the Pacific Ocean and were carried as far as North America. The minerals transported in this manner are believed to provide nutrients for both oceanic and land ecosystems. The left-hand and middle images are from Terra orbits 2,967 and 6,928 respectively. They are approximately 380 kilometers (236 miles) in width. The right-hand image covers an area roughly 250 kilometers (155 miles) wide by 470 kilometers (292 miles) high. Analyses of images such as these constitute one phase of MISR's participation in the Asian-Pacific Regional Aerosol Characterization Experiment, an international campaign aimed at studying the offshore transport of airborne particles from the Asian continent. More information about this international endeavor is available online at http://saga.pmel.noaa.gov/aceasia/ . MISR, built and managed by NASA's Jet Propulsion Laboratory, is one of several Earth-observing experiments aboard Terra, launched in December 1999. MISR acquires images of the Earth at nine angles simultaneously, using nine separate cameras pointed forward, downward, and backward along its flight path. More information about MISR is available at http://www-misr.jpl.nasa.gov . JPL is a division of the California Institute of Technology in Pasadena.

Gobi Dust Storm
Title Gobi Dust Storm
Description In early and mid-April 2006, waves of dust washed out of the Gobi Desert and spread across eastern China, the Korean Peninsula, and Japan. According to news reports, a dust storm that hit South Korea [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13484 ] over the weekend of April 8 was the worst the country had seen in four years. This pair of images shows a massive wave of dust that blew out of deserts in north-central China on April 10, 2006. The top image, captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] on April 7, 2006, shows the landscape of north-central China, including two large, sandy deserts that are part of the Gobi Desert region. Just a few days later, an image from the MODIS sensor on the Aqua [ http://aqua.nasa.gov ] satellite shows that the area was completely hidden by a wave of bright dust that reached beyond the Yellow River. Gobi dust is whipped eastward with prevailing winds by spring storms and can spread all the way to the United States. The storms can be hazardous to public health both in terms of air quality and visibility. In addition, the dust storms can devastate croplands and contaminate sensitive electronic equipment. Dust storms in China are on the rise, probably as a result of land degradation, such as deforestation and overgrazing, and drought. The Chinese government has undertaken a large reforestation effort to combat the spread of deserts and to mitigate the effects of dust storms, particularly around urban areas such as Beijing. The large images above are provided at MODIS' maximum spatial resolution (level of detail) of 250 meters per pixel. The MODIS Rapid Response Team provides daily images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?FAS_China3 ] of this area of China in a variety of formats and resolutions.

Smog and Sand over Beijing
Title Smog and Sand over Beijing
Description Thick sand from one of China's famed sandstorms clouded the air over Beijing on April 17, 2006. The storm swept east from the border region between China and Mongolia and blanketed cities across China with gritty yellow sand. The storm was the eighth and worst such storm of 2006, reported the BBC. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] flying onboard the Terra [ http://terra.nasa.gov/ ] satellite took this picture on the morning of April 17. In this image, a thick band of tan dust obscures the view of the land surface below. Immediately east of the sandstorm are thick clouds, colored tan by the airborne dust. Along the coastlines, brownish sediments from both China and the Korean Peninsula cloud the Yellow Sea. As Terra captured this image, The Korea Times predicted that the storm would strike Korea on the evening of April 17, 2006.

Spring Dust Storms Scour Chi …
Title Spring Dust Storms Scour China
Description Just as flowering and greening plants, migrating birds, and flooding herald the coming of spring in the Northern Hemisphere, dust storms are a sign of spring in northern China. Cold fronts from Siberia to the north bring strong winds to the deserts of Inner Mongolia. The winds pick up sand and carry it southeast over the densely populated region surrounding the Bo Hai and the Yellow Sea. In the most powerful storms, the dust may be carried all the way across the Pacific Ocean to North America. The storms subside in mid-May when warm air moves up from the southwest. On April 20, 2005, the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured this photo-like image of dust over the Yellow Sea. The storm that generated this dense brown cloud of dust covered much of Northern China, including Beijing, with a dusty haze. The dust blew east into Korea, where officials referred to it as the worst dust storm so far this year. The winds are expected to calm on Friday, April 22, 2005. Not all of the brown seen in this image is caused by airborne dust. Near the shores, sediment colors the water of the Yellow Sea. The brown of the sediment fades to green as the dirt is diluted in the sea. The high-resolution image provided above is at MODIS' maximum resolution of 250 meters per pixel. The MODIS Rapid Response Team provides the image in additional resolutions. NASA image courtesy Jeff Schmaltz, MODIS Land Rapid Response Team [ http://rapidfire.sci.gsfc.nasa.gov ] at NASA GSFC.

Title Widespread Smoke, Fires Across Eastern China
Description Many fires (red pixels) were burning across the Henan Province in eastern China on June 7, 2002, filling the skies with a thick pall of greyish smoke as far north as Beijing. The smoke appears to be blowing northeastward over the Yellow Sea toward Korea and Japan. This true-color image was acquired by the Moderate Resolution Imaging Spectroradiometer [ http://modarch.gsfc.nasa.gov ] (MODIS), flying aboard NASA?s Terra [ http://terra.nasa.gov ] satellite. Please note that the high-resolution scene provided here is 500 meters per pixel.
