Analyses were done with a variety of methods. For HCl, HF, NO, and NO2, an equivalent width method was used. For CF2Cl2, CH4, C2H6, H2O, N2O, and CO2, an interactive graphical technique for fitting observed and calculated spectra was used. For O3, ClONO2, and HNO3, the SFIT least squares fitting program (Rinsland) was used. Analyses were done by Coffey, Mankin, James Hannigan, and Aaron Goldman. -- Spectral regions used for the fits: CF2Cl2 921 - 923 cm-1 C2H6 2970 - 2995 cm-1 CH4 2920 - 2925, 2970 - 2995 cm-1 ClONO2 780.0 - 780.5 cm-1 CO2 2010 - 2030 cm-1 H2O 2970 - 2995 cm-1 HCl 2920 - 2950 cm-1 HF 4039 cm-1 HNO3 867-870 cm-1 N2O 1180 - 1194 cm-1 NO 1840 - 1920 cm-1 NO2 1600 - 1610 cm-1 O3 1141 - 1144 cm-1 -- For the source gases and ozone the profiles were from Smith, NASA TM 83289. In the arctic region, these profiles were lowered by 4 km. For the other gases, profiles were from JGR, 94, 16597, 1989. Line parameters were from the AFGL92 compilation with update of the chlorine nitrate and nitric acid lines from Aaron Goldman. -- The precision, where reported, is the standard deviation of retrievals made on a number of spectral features, except for ClONO2, where it is an estimate based on the residuals in the fit. -- For the source gases, the column reported is the integrated value above 200 mb for the scaled profile that best matches the observations; thus the effect on the column of changing aircraft altitude is removed.
