The data may be processed in other ways upon request. Although mixing ratios are output on a 1km grid, actual vertical resolution is 4km. For some species the profile may be undersampled, leading to anomalies in tracer-tracer correlations. Horizontal resolution is 200-400km, depending on the vertical mixing ratio profile. For a description of the FIRS-2 spectrometer and retrieval algorithm, see D.G. Johnson, K.W. Jucks, W.A. Traub, and K.V. Chance, Smithsonian stratospheric far-infrared spectrometer and data reduction system, Journal of Geophysical Research, 3091-3106, 1995. This file contains a subset of the molecules observed by FIRS-2; other species are available upon request, including OH, HO2, H2O2, HCl, HOCl, ClNO3 (as of the 5/94 flight), N2O5 (as of 5/94), NO2, and O2. Additional molecules available as of the 4/97 flight include HNO4, CCl4, CFC11, CFC12, CH3Cl, HCFC22, OCS, SF6, and CH4. Uncertainty quoted below is estimated 1-sigma precision, including fitting residuals, temperature and pressure errors, and feedthrough errors. Systematic errors are dominated by the uncertainty in the spectral line parameters, estimated to be as follows: H2O, 7%; O3, 3%; N2O, 3%; HNO3, 10%; HF, 4%; delta(18O), 70 per mil; delta(D), 40 per mil. For more information, contact Dave Johnson (dgj@cfa.harvard.edu) or Ken Jucks (jucks@cfa.harvard.edu). NOTE: When precision is sufficiently low the retrieval process will occasionally produce negative mixing ratios. While this is meaningful in a statistical sense, real mixing ratios cannot be negative, and these values should be converted to upper limits by ignoring the negative mixing ratio and taking twice the standard error as the 95% confidence limit.
