CFC-11 was corrected for a non- linearity in its calibration curve. The standards used were 131.4 ppt for CFC-11 and 55.6 ppt for CFC-113. A time shift compared to ozone was also applied of -30 seconds. CFC-113 concentrations excluded from first submission due to contamination in the first10 calibration samples. Contamination resulted from not flushing the cal lines prior to the flight. We have replaced the 10 bad cal values with a constant in order to provide estimates for the first 20 air concentrations. The remaining concentrations were unaffected by the contamination. 1 GMTs CFC-11 (ppt) CFC-113 (ppt) 50574 253.4 40.3 50694 257.4 43.7 50934 255.1 49.7 51054 259.5 51.6 51294 270.0 58.3 51414 253.8 57.1 51653 230.0 40.6 51773 231.4 53.0 52013 198.5 46.8 52133 170.4 44.7 52373 177.1 46.1 52493 171.8 45.3 52733 165.4 42.8 52853 163.2 46.8 53093 127.6 43.4 53213 115.7 41.8 53453 107.3 42.4 53573 101.6 46.8 53813 115.6 47.1 53933 124.3 47.1 54173 116.7 35.9 54293 125.6 33.3 54533 117.4 30.4 54653 114.4 29.3 54893 82.4 28.0 55013 70.1 30.4 55253 98.2 34.0 55373 89.6 33.4 55613 59.5 32.5 55733 47.7 28.1 55973 93.3 34.4 56093 95.0 30.9 56332 117.3 34.4 56452 112.6 35.2 56692 117.9 40.0 56812 129.0 37.2 57052 130.3 40.0 57172 112.7 38.3 57412 108.7 41.5 57532 112.7 48.1 57772 151.8 50.6 57892 146.9 43.3 58132 172.5 45.2 58252 165.8 42.0 58492 173.2 48.3 58612 184.0 45.4 58852 161.5 45.5 58972 163.1 38.9 59212 137.0 40.1 59332 136.2 46.4 59572 128.8 43.8 59692 135.0 42.0 59932 124.8 40.9 60052 121.3 41.0 60292 119.0 43.3 60412 109.3 42.0 60652 134.9 43.4 60772 129.3 44.5 61011 115.9 45.3 61131 96.9 43.4 61371 98.1 41.8 61491 94.0 38.8 61731 83.0 41.3 61851 88.6 46.4 62091 106.7 46.4 62211 104.9 43.5 62451 178.2 53.1 62571 184.6 50.7 62811 122.7 47.5 62931 131.2 50.3 63171 176.4 43.8 63291 171.2 42.8 63531 148.6 36.7 63651 106.5 38.2 63891 114.5 39.8 64011 133.2 41.7 64251 137.7 46.1 64371 137.6 47.6 64611 119.9 45.0 64731 130.1 45.5 64971 124.9 44.5 65091 127.9 44.6 65331 126.1 42.4 65450 126.2 46.3 65690 124.6 45.7 65810 124.4 49.5 66050 115.4 50.0 66170 118.3 45.0 66410 122.4 47.2 66530 109.8 45.4 66770 119.3 48.2 66890 111.8 47.6 67130 127.1 51.4 67250 120.2 46.6 67490 123.1 48.4 67610 107.4 48.0 67850 102.5 47.7 67970 97.8 42.5 68210 111.9 42.5 68330 111.5 43.8 68570 115.4 47.2 68690 101.9 45.1 68930 113.4 42.8 69050 120.1 46.8 69290 98.3 48.9 69410 102.6 45.5 69650 108.2 47.8 69770 104.9 43.0 70009 102.2 43.6 70129 140.5 48.5 70369 151.0 52.2 70489 144.6 50.0 70729 170.2 52.8 70849 180.9 51.8 71089 235.8 57.8 71209 255.9 62.5 71449 258.6 60.6 71569 257.0 66.9 71809 261.7 57.5 71929 270.2 55.3
