Global pollution simulator on Portland

Domes will recreate smell, heat and haze in notoriously polluted cities
An art exhibition on Portland will offer visitors the chance to experience pollution levels in five global cities and its impact on climate change. Visitors will pass through "inter-connected pods" comparing simulated temperatures and air quality in Tautra (Norway), London, Sao Paulo, Beijing and New Delhi. The exhibit is located at the Stadium Bowl on Portland and was inspired and created by internationally renowned artist, Michael Pinsky.
