NASA planes fly over Taiwan in air-quality testing

Taipei Times - Two NASA aircraft yesterday flew over Taiwan to collect air quality samples as part of a joint study with countries across the Asia-Pacific region, the Ministry of Environment said.

The four-hour mission would generate a 3D map of air pollution in central and southern Taiwan, the ministry wrote in a news release published hours before the survey.
