Planetary Wave Examined From Ozone Profile Data Of Odin-OSIRIS

The zonal wind will be produced by the longitudinal and latitudinal disturbance of the planetary waves. The disturbance of the planetary waves can cause the longitudinal and latitudinal transportation of O3. Thus, there is periodic change of O3 by the effect of the planetary waves in the winter and spring of the northern hemisphere's middle and high latitude. Otherwise, the periodic change of O3 can be used to detect the planetary waves. In this study, the spectral analysis of the Odin-OSIRIS ozone profiles data is conducted to detect the fluctuation characteristics of the planetary waves.Now we mainly use the atmosphere composition and meteorological data to study the planetary waves. They are separately from the surface meteorological elements, the upper air meteorological elements, and atmospheric remote sensing. So far, lots of high resolution atmospheric observation data are obtained at global scale with the launch of meteorological satellite and many other satellites. In this study, the Odin-OSIRIS ozone vertical profiles density data are used to detect the planetary waves.Fast Fourier Transform (FFT) methods and the Method of Maximum Entropy (MME) are used to spectral analysis of evenly spacing data. Lomb-Scargle periodogram method, Singular Value Decomposition Method, and Least Square Fitting Method have also suggested to spectral analysis of the unevenly spacing data. Based on unevenly spacing of Odin-OSIRIS ozone profiles density data, these methods are explored for this study. Lomb-Scargle periodogram method can not be used to analyze the number of the waves. The wave number is an important parameter of the planetary waves, Singular Value Decomposition Method and Least Square Fitting Method are thus used to analyze the Odin-OSIRIS ozone profiles density data.The linear LS fit method and Singular Value Decomposition Method are employed respectively for the OSIRIS profile-data at altitudes (38km and 40km) within the latitude bins (350-450N) and (450 -550N) on these days number: 75-105 days of the year of 2002, it shows that the westward propagating, nearly 10-day periods (3 cycles per 30 days). We can obtain the same result with the singular value decomposition method and the Least Square Fitting Method, but the singular value decomposition method's operation speed is faster than Least Square Fitting Method. The singular value decomposition method is employed for the OSIRIS profile-data on these days number: 45-75,105-135 days of the year of 2002 and 75-105days of the year of 2003-2006, it shows that the westward propagating, nearly 10-day periods (3 cycles per 30 days). And planetary waves (mode +1) are present at two altitudes 38km and 40km within two latitude bins on these days number: 75-105 days of the year of 2003 and 2004, but some characteristics of them is not clearly.Planetary waves (mode +1) are present at two altitudes 38km and 40km within two latitude bins, which consistent with planetary waves that detected by the MFR (medium frequency radar) data and UKMO data at the same day. Therefore, it is available that the Odin-OSIRIS ozone profiles density data can be used to detect the planetary waves.
