Chinese officials are seeking air pollution tips from Research Triangle Park to help fight smog and other problems in Beijing.
It comes just a year before Beijing hosts the Olympic games. A group of Chinese air modelers, engineers and meteorologists recently completed three weeks of training at R-T-I International, a research institute based at Research Triangle Park.
The officials learned to use state-of-the-art computer modeling to forecast air pollution. Beijing's goal is to meet national air standards before it hosts the Olympics.
The city is trying to combat particle pollution and high ozone levels. Environmental improvement efforts in Beijing have been hampered by the country's rapid growth, a high level of construction and increasing number of vehicles on the roads.
