A Spectral Analysis of the Sunspot Time Series Using the Periodogram
نویسنده
چکیده
The sunspot number time series was used to examine different methods of the periodogram as a spectrum estimator. The periodogram was used as the benchmark to compare the results of the sunspot cycle period estimate to the modified periodogram, the Blackman-Tukey method of periodogram smoothing, the Welch-Bartlett method of periodogram averaging and the Multitaper method. The Welch-Bartlett method resulted in the closest estimate to the modern sunspot cycle period estimate of 10.4883 years/cycle.

In the present work, we introduce and explain a method of solution of the radiative transfer equation based on a thin cloud model. The efficiency of this method to retrieve dynamical chromospheric parameters from Stokes I profiles of Ca II 854.2 nm line showing spectral emission is investigated. The analyzed data were recorded with the Crisp Imaging Spectro-Polarimeter (CRISP) at Swedish 1-m So...

متن کاملSpectral Estimation of Stationary Time Series: Recent Developments
Spectral analysis considers the problem of determining (the art of recovering) the spectral content (i.e., the distribution of power over frequency) of a stationary time series from a finite set of measurements, by means of either nonparametric or parametric techniques. This paper introduces the spectral analysis problem, motivates the definition of power spectral density functions, and reviews...

متن کاملAveraged periodogram spectral estimation with long memory conditional heteroscedasticity
The empirical relevance of long memory conditional heteroscedasticity has emerged in a variety of studies of long time series of high frequency nancial measurements. A reassessment of the applicability of existing semiparametric frequency domain tools for the analysis of time dependence and long run behaviour of time series is therefore warranted. To that end, this paper analyses the averaged p...
