Solar Activity Record from Archeomagnetic Data

摘要

Each of the available solar activity (SA) proxy data (historical notes, radio nuclides 14C and 10Be production) are contaminated by their specific noise factors. So, any additional proxy with its independent noise factors will essentially increase the accuracy of composite SA restorations. It is proposed here that archaeomagnetic measurements 95% confidence interval (α95) may serve as new proxy for the SA estimation in the past. This proxy is compared with other available proxies during the years 1500–2000.
