Summary edit
DescriptionMauna Loa Tetrafluoromethane.jpg |
English: Graph shows the concentration of tetrafluoromethane (CF4, carbon tetrafluoride) in earth's atmosphere versus time. X-axis data interval is weekly, starting September 2014. Y-axis concentration is parts per trillion). Atmospheric samples were gathered within evacuated flasks from the Mauna Loa Observatory Hawaii, then sealed and transported to Boulder Colorado for the analysis. Similar observations gathered from other remote sampling sites around the world validate that these data represent a well-mixed gas throughout the atmosphere.
