Estimated accuracy for ClOOCl and ClONO2: +/- 40 percent, 2 sigma. Contact investigators for more information. This version of the inorganic chlorine data differs from the preceding version in that the ClO measurements have been increased on average by up to 25 per cent. This pressure and temperature dependent revision results from the inclusion of the ClOO+NO reaction in the calculation of the yield of Cl atoms from the titration of ClO with NO. The ClOOCl and ClONO2 results are unaffected. In addition we are reporting zero values for those flights where our instrument was operating properly but ClOOCl and/or ClONO2 were demonstrably below the detection limit (approx. 20 ppt for each) for the entire flight. Previously we reported nan values for these flights. Thus the ClOOCl measurements for the flights of 20000106, 20000109, 20000111, and 20000316 are zero values. The flight of 20000123 reports nans because we had an instrument operation failure on that flight. For ClONO2 the flights of 20000120, 20000123, 20000131, 20000202, 20000203 now are zero values. 2 ******************** Data ***************** Time ClO ClOOCl ClONO2 55090.75 5.5 0.0 999999.9 55125.75
