Haze in Eastern China
| Title |
Haze in Eastern China |
| Description |
Haze collected south of Beijing on August 13, 2007. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] flying on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured this image the same day. In this image, haze snakes its way northward from an especially heavy concentration just east of the Yellow Sea. The haze likely resulted from a combination of industrial smog and smoke from wildfires. Weather patterns may have played a role in trapping the haze in this region, Typhoon Pabuk made landfall near Hong Kong and traveled northward along the coast.

Haze over Beijing |
| Description |
Haze collected over the Beijing region on July 27, 2007. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] flying on NASA's Terra [ http://terra.nasa.gov/ ] satellite took this picture the same day. In this image, the haze mingles with clouds, appearing only slightly darker in color and more diffuse in shape. Haze is thick enough to completely hide Beijing, and low-lying haze clings to the river valleys north of the city.

Haze over China
| Title |
Haze over China |
| Description |
Thick haze collected over the Beijing region in late March 2007. Earlier that month, the BBC News reported that an international team of scientists had documented how increasing pollution in China led to decreasing rainfall over the region. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] flying onboard the Aqua [ http://aqua.nasa.gov ] satellite captured these images of the Beijing region on March 22, 2007. The top image is a "true-color" picture, similar to a digital photo. The bottom, "false-color," image uses a combination of visible and infrared light to more clearly show vegetation, water, and clouds. Even sparse vegetation appears bright green, while water appears deep blue (bright blue when tinged with sediment). Clouds dominated by water droplets appear white, while clouds made of ice crystals appear light blue. The false-color image highlights water bodies, perhaps aqua-culture ponds, that are all but invisible in the true-color image, especially along the shores of the Bo Hai. While vegetation and water show up more clearly in the false-color image, haze is much more transparent. Although dingy gray haze dominates the true-color picture, it is all but invisible in the false-color view. The haze "disappears" in the infrared-enhanced image because tiny haze particles do not reflect longer-wavelength infrared light very well, making this type of image useful for distinguishing haze from clouds. The bank of clouds in the upper right corner shows up clearly in both pictures. As China industrializes, factories, power plants, and automobiles all contribute to pollution in the region. In examining pollutants and rainfall, the team of scientists examined records covering more than 50 years, concluding that pollution decreased precipitation at Mount Hua near Xi'an in central China. They concluded that when conditions are so hazy that visibility is reduced to less than 8 kilometers (5 miles), hilly precipitation can drop by 30 to 50 percent. When moist air passes over mountains, it usually cools and forms raindrops, but heavy pollutant concentrations cause the clouds to hang on to their moisture.

Haze over China

Haze over China |
| Description |
Just days after thick haze [ http://earthobservatory.nasa.gov/Newsroom/NewImages/images.php3?img_id=17591 ] collected over the Beijing region, more haze clouded the skies over Bo Hai, east of the capital city. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] flying onboard the Terra [ http://terra.nasa.gov ] satellite captured these images of Bo Hai on March 26, 2007. The top image is a "true-color" picture, similar to a digital photo. The bottom image is a "false-color" picture that uses a combination of visible and infrared light to give a clearer picture of vegetation, water, and clouds. Besides clearly showing vegetation, water, and clouds, the false-color image, when paired with a true-color image, helps the viewer discern haze. In the top image, thick haze dominates the image, but the same haze barely appears in the bottom image. The pollutants comprising most of the haze have little water content, rendering them largely invisible in the false-color picture.

Haze over Eastern China

Haze over Eastern China |
| Description |
One day after a thick plume of haze crept toward Beijing, much of eastern China was obscured on October 23, 2007. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Aqua [ http://aqua.nasa.gov ] satellite took this picture the same day, showing haze dense enough to completely block the view of the land surface below. As on the previous day, the haze largely avoided the Taihang Shan Mountains southwest of the capital city, although fingers of haze crept westward toward the peaks. Thick haze spread from Beijing southward, well past the coast of the Yellow Sea. NASA image courtesy the MODIS Rapid Response Team [ http://rapidfire.sci.gsfc.nasa.gov ] at NASA GSFC.

Haze over Eastern China |
| Description |
A nearly opaque plume of haze snaked through eastern China on October 20, 2007. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] satellite took this picture the same day. This image shows thick haze hugging the slopes of the Taihang Shan Mountains as it pushes north toward Beijing. Just south of the city, however, the haze veers off to the east, blowing over Bo Hai. The haze likely results from industrial and vehicular emissions as China struggles to balance economic growth with a healthy environment. According to news reports, lung cancer rates in China rose 26.9 percent in males and 38.4 percent in females between 2000 and 2005, and air quality was expected to pose the greatest challenge to athletes in the 2008 Olympics.

Springtime Aerosols over Eas

Springtime Aerosols over Eastern Asia |
| Description |
March 31, 2007, marked opening ceremonies for the first "Green China Day," established to increase awareness of the need for environmental protection. As reported by ShanghaiDaily.com, however, the ceremony in Beijing saw an unwelcome guest: Gobi Desert dust. [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14194 ] Roughly 2,000 kilometers south of the capital city, air quality also suffered, in this case from fires [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14193 ] in Southeast Asia. The Ozone Monitoring Instrument (OMI) [ http://aura.gsfc.nasa.gov/instruments/omi/index.html ] flying onboard the Aura [ http://aura.gsfc.nasa.gov/index.html ] satellite measures the thickness of light-absorbing aerosols—tiny solid or liquid particles suspended in the atmosphere. OMI captured these images on March 30 (top) and March 31 (bottom). The images superimpose a color-coded scale of aerosol thickness onto a natural-color image of eastern Asia, the Sea of Japan, and the western Pacific Ocean. These images track the eastward movement of aerosols into the Beijing region, and show aerosols blowing eastward out of Southeast Asia, dissipating as they travel. Red areas indicate where aerosols are thickest or where aerosols float over reflective clouds, which tend to make the aerosol concentration appear more intense than it actually is. Aerosols south of 30 degrees latitude likely result from smoke from biomass burning. To the north, aerosols probably result from dust. In both cases, the time of year plays a role. Southeast Asian farmers often prepare for the growing season by setting agricultural fires each spring. Accidental fires also spring up readily at this time of year. Meanwhile, Gobi Desert dust storms generally peak in the spring then gradually decline throughout the summer. The March 31 dust storm that blanketed Beijing marked the first such storm of 2007.
