Unusual activity of the Sun during recent decades compared to the previous 11,000 years
TL;DR: A reconstruction of the sunspot number covering the past 11,400 years is reported, based on dendrochronologically dated radiocarbon concentrations, and it is pointed out that solar variability is unlikely to have been the dominant cause of the strong warming during the past three decades.
Journal ArticleDOI
A History of Solar Activity over Millennia
TL;DR: A review of present knowledge of the long-term behavior of solar activity on a multi-millennial timescale, as reconstructed using the indirect proxy method is presented in this paper, along with an overview of special indices used to quantify different aspects of variable solar activity, with special emphasis upon sunspot number.
Journal ArticleDOI
Heliospheric modulation of cosmic rays: Monthly reconstruction for 1951–2004
TL;DR: In this article, the authors presented a series of monthly values of the modulation potential ϕ since February 1951, reconstructed using the data from the worldwide neutron monitor network and calibrated with precise balloon and space-borne direct measurements of cosmic ray energy spectrum.
Journal ArticleDOI
Grand minima and maxima of solar activity: new observational constraints
TL;DR: In this paper, the authors present an updated reconstruction of sunspot number over multiple millennia, from 14 C data by means of a physics-based model, using an updated model of the evolution of the solar open magnetic flux.

TL;DR: In this paper, the authors presented a physically consistent reconstruction of the total solar irradiance for the Holocene, based on the SATIRE (Spectral And Total Irradiance REconstruction) models.
