Appendix C: First Global Observations of Atmospheric COClF from the Atmospheric Chemistry Experiment Mission

摘要: Carbonyl chlorofluoride (COCIF) is an important reservoir of chlorine and Fluorine in the Earth's atmosphere. Satellite-based remote sensing measurements COCIF, obtained by Received revised form Atmospheric Chemistry Experiment (ACE) for a time period spanning February 2004 through April 2007, have been used global distribution study. There strong Accepted 18 2009 source region COCIF tropical stratosphere near 27 km. A layer enhanced spans low- to mid-stratosphere over all latitudes, with volume mixing ratios 40-100 parts Per trillion volume, largest tropics decreasing toward poles. The ratio profiles are nearly zonally symmetric, but they exhibit small hemispheric asymmetry that likely arises from parent molecule CCl3F. Comparisons made set situ stratospheric mid-1980s predictions 2-D model.
