Smog in Shanghai, China

Southeast Asia

NO2 levels in Southeast Asia are far lower than in the U.S., Western Europe and East Asia.  Nevertheless, there were areas of increases in some countries, such as Thailand and Vietnam, including the expanding industrial parks of the cities of Hanoi and Haiphong.  Large decreases occurred over a few cities, such as Jakarta (Indonesia), though the causes are unknown.
