High resolution stratospheric tracer species maps were generated using a locally developed version of the Morris et al (1996) algorithm. In particular, tracer species measured by the Cryogenic Limb Array Etalon Spectrophotometer -CLAES- flown on board UARS were used. Daily maps at isentropic levels corresponding to the stratosphere were produced throughout the lifetime of CLAES (January 1992-May 1993).
Normally maps such asthose obtained above can be analyzed using spectral analysis methods. However one of the problems inherent to 'classical' spectral techniques such as FFT is that the information obtained corresponds the frequencies during the whole of the sample period, but the time of occurrence of particular spectral lines is lost in the process. The latter information is very valuable when trying to understand the interactions between waves, wave propagation, wave-mean flow relationships etc. Such information can be obtained when the data analysed using wavelet techniques.
Such wavelet techniques are applied here in the analysis of the high resolution CLAES tracer maps. The results of this application are intepreted and discussed. THey are also copared with standard FFT analysis
