Cleanest air on earth

Elke Bergholz is inside the Clean Air Sector outside the Atmospheric Research Observatory. She is carrying a field case that contains special bottles for collecting CO2. This area has the cleanest air on earth and is used as the control. No plane is allowed to fly over this area and no one is allowed to enter this are without permission. In the background is the ARO building. The bottles are then shipped to the NOAA lab in Boulder, Colorado.
