An  international team of scientists is studying the problem of pollution and  dust in Asia. One- hundred- thirty scientists from twelve countries have g athered in the western Pacific area to observe thick dust storms. They wil l observe the dust storms as they mix with some of the world's heaviest po llution. The thickest dust storms in recent years were reported in Beijing , China and other Asian cities last spring. The dust storms came from dese rts in China and (1) Mongolia. This year, similar dust storms have begun m oving east toward large Asian cities and the northwest Pacific Ocean. The  dust storms happen in winter over deserts high above sea level. In the spr ing, the storms move east, over large cities in China, Japan and Korea. By  summer, rainstorms break up the dust and help reduce pollution in the air . The scientists plan to observe the dust storms through the middle of May . They are using research ships, airplanes, satellites and instruments on  the ground to gather information. The study is known as the (2)Aerosol Cha racterization Experiment, or ACE-Asia. The American National Center for At mospheric Research reported on the study. Aerosols are very small particle s in the air. The scientists are studying aerosols that contain sulfate an d carbon, that are produced by the burning of soft coal, wood and plants.  Barry Hubert of the University of Hawaii is the lead investigator for the  study. He says developing nations in Asia use a mixture of fuels that are  not used in other areas. Richard Dirks of the University Corporation for A tmospheric Research is the director of field operations for the study. He  will supervise the study from project headquarters in Japan. He says the s tudy will help scientists better understand how human activities affect Ea rth's (3) climate. He notes that the (4) project involves countries that h ave not worked together in the past. ACE-Asia is the third in a series of  pollution studies. The first was based in (5) Tasmania, Australia. The goa l of that study was to measure pollution levels in a clean environment. Th e second study was in the Canary Islands. Scientists there studied polluti on from Europe mixing with dust from the Sahara Desert. This year, the sci entists are measuring the heaviest aerosol pollution on Earth.
