Paris Visualizes Air Quality Via Color-Changing Balloon
Airparif recently deployed a giant helium balloon that will provide Parisians with an at-a-glance indication of both atmospheric and inner-city air quality. The Balloon is the first of its kind and will employ an innovative color-changing system to broadcast an important environmental message.
