Scaling Properties and Persistence of Long-Term Solar Activity

The long-range correlations associated with the presence of persistence are investigated by applying detrended fluctuation analysis (DFA) on three different proxies long-term solar activity. considered datasets a sunspot number reconstruction (SNR04) obtained from atmospheric activity cosmogenic isotope 14C derived tree rings, total irradiance (TSIR12) several 10Be ice core records Greenland and Antarctica in combination global record rings new multi-proxy (SNR18), also production series. DFA scaling exponents found for time series similar (lying range between 0.70 0.77) ranges comparable. These results indicate persistence, substantial agreement findings previous studies carried out other indices proxies.
