English: Graph shows the hemispheric and global mean concentrations of trichlorofluoromethane (Freon 11, CFC-11, R-11) in earth's atmosphere versus time. X-axis data interval is monthly. Y-axis concentration is parts per trillion. The data represent a mean of combined data from the HATS (Halocarbon and Atmospheric Trace Species) programs; which include up to 15 sampling sites that are distributed over the northern and southern hemispheres.
