Atmosphere was an interactive installation that was presented at the City Hall Square in Copenhagen for the international climate summit, COP15. The installation measured the air's CO2 content with sensors at three different locations in Copenhagen. The installation consisted of a box-shaped display on which LEDs gave artists the opportunity for visual expression complemented by a sound system that added an auditory layer. In addition to this, the audience had access to the installation through websites on which they could view current CO2 levels in Copenhagen.
A new version of the project was shown in Sydney, Australia, in 2010.
