Summary
| Description |
English: Graph shows the concentration of chlorodifluoromethane (HCFC-22, R-22, CHClF2) in earth's atmosphere versus time and latitude. X-axis data interval is monthly. Y-axis concentration is parts per trillion. Atmospheric samples were gathered within evacuated flasks from 8-12 ground stations distributed over the northern (positive latitudes) and southern hemispheres, then sealed and transported to Boulder Colorado for analysis. Most emissions originate at northern latitudes, and are mixed through the troposphere of both hemispheres after about 1-2 years. Data sampling and analysis by: |
