More than 100 international atmospheric experts from the US, Europe, and Japan have gathered in Taipei for the 2026 7-Seas Workshop. Marking the 20th anniversary of Taiwan's world-class Lulin Atmospheric Background Station, researchers are revealing key data gathered from joint 3D tracking experiments with NASA Aeronet. The findings show a clear line between high-altitude transboundary smog and domestic ground pollution—sparking fresh demands from the environment ministry for tighter local traffic emission controls.
