Data analysis

The data analysis is described in detail in Meier (1997) and Meier et al. (1996 and 1998). Details of the Wollongong site and the preparation of auxiliary data such as meteorological data is given in Griffith et al (1998) and in our companion presentation P/2 3-13. Briefly, the analysis software used thus far for all but the latest results is SFIT-1 version 1.09e (e.g. Rinsland et al., 1988) (yields total column amounts only). Profile retrievals that yield volume mixing ratio profiles were performed with the new SFIT2 vers. 3.74 algorithm (Connor et al., 1998 and 1995, Rinsland et al, 2000) for the analysis of N₂O and a re-analysis of the Wollongong water vapour data. The meteorological data is based on local radio sonde profiles splined into NMC data above ceiling altitude. The forward model and ray-tracing was performed with the improved fscatm code version 2.02 as of Aug 2000. All other scripting and auxiliary programs are taken from the SFIT-Tools suite (http://www.uow.edu.au/~arndt/sftools.htm).
