Comparative Spectral Analysis and Correlation Properties of Observed and Simulated Total Column Ozone Records
International audience We present a statistical analysis of total column ozone records obtained from satellite measurements and from two global climate chemistry models on global scale. Firstly, a spectral weight analysis is performed where the relative strength of semiannual, annual and quasi-bienn...
