摘要: We report infrared ground based total column measurements of the stratospheric fluorine reservoir gases COF2 and HF above Lauder, New Zealand (45°S, 167.8°E) obtained between April 1993 January 1994. The average retrieved columns are 2.81(±0.56)×1014 9.91(±1.09)×1014 molecules/cm², respectively. daily correlated; this correlation is likely result dynamics. HF/COF2 ratio on days with both 3.63 (±0.55). Comparison model calculations implies that quantum yield for photolysis near unity. Our measured higher than all previously reported values, but inconsistencies among earlier uncertainty in latitudinal gradient preclude an accurate determination long-term trend.
