CORDIS-JRC

Air quality is not a local problem. Like clouds moving through the sky, pollution is transported from one location to another by wind patterns in the atmosphere. With each breath we inhale vital oxygen, but also small amounts of potentially harmful gases and small particles. These components directly affect our health, and can be carcinogenic. Observations, both from satellite and from the ground, can provide a snapshot of the air quality. The trouble is that they have no real predictive capability.
