Direct observations of sunspot numbers are available for the past four centuries, but longer time series are required, for example, for the identification of a possible solar influence on climate and for testing models of the solar dynamo. Here we report a reconstruction of the sunspot number covering the past 11,400 years, based on dendrochronologically dated radiocarbon concentrations. We combine physics-based models for each of the processes connecting the radiocarbon concentration with… Expand

Prediction of solar activity for the next 500 years
[1] Recently, a new low-noise record of solar activity has been reconstructed for the past 9400 years by combining two 10Be records from Greenland and Antarctica with 14C from tree rings [Steinhilber… Expand
Solar activity reconstructed over the last 7000 years: The influence of geomagnetic field changes
[1] The long-term solar activity, as manifested by sunspot number, has been recently reconstructed on multi-millennium time scales by S. K. Solanki et al. (2004) from the measured concentration of 14… Expand
A new approach to the long-term reconstruction of the solar irradiance leads to large historical solar forcing
Context. The variable Sun is the most likely candidate for the natural forcing of past climate changes on time scales of 50 to 1000 years. Evidence for this understanding is that the terrestrial… Expand
Was the solar activity in the last 100 years abnormally high? On the quality of modern solar paleoreconstructions
A technique for verifying the currently available reconstructions of solar activity in the preinstrumental epoch (prior to 1615 AD), covering time intervals up to 10 000 years, has been developed and… Expand
The Importance of Long-Term Synoptic Observations and Data Sets for Solar Physics and Helioseismology
A casual single glance at the Sun would not lead an observer to conclude that it varies. The discovery of the 11-year sunspot cycle was only made possible through systematic daily observations of the… Expand
Taking the pulse of the Sun during the Holocene by joint analysis of 14C and 10Be
We have studied solar variations during the Holocene (i.e., last similar to 11,700 yr) by combining a new model of the Earth's dipole moment with C-14 data from the IntCal04 record and 10 Be data… Expand
Revisiting the Sunspot Number A 400-Year Perspective on the Solar Cycle
Our knowledge of the long-term evolution of solar activity and of its primary modulation, the 11-year cycle, largely depends on a single direct observational record: the visual sunspot counts that… Expand
Global solar activity on long time scales
AbstractWe report the results of the application of our approach to study the behavior of solar activity in the past, where: When reconstructing the variations of solar activity, geomagnetic… Expand

Correlation between solar activity and the local temperature of Antarctica during the past 11,000 years

Reconstruction of solar activity for the last millenium using 10Be data
In a recent paper (Usoskin et al. 2002a), we have reconstructed the concentration of the cosmogenic 10 Be isotope in ice cores from the measured sunspot numbers by using physical models for 10 Be… Expand
Millennium-scale sunspot number reconstruction: evidence for an unusually active sun since the 1940s.
TLDR
Records of the (10)Be concentration in polar ice are used to reconstruct the average sunspot activity level for the period between the year 850 to the present, showing reliably that the period of high solar activity during the last 60 years is unique throughout the past 1150 years. Expand
Long-term indirect indices of solar variability
Continuous direct records of solar variability are limited to the telescopic era covering approximately the past four centuries. For longer records one has to rely on indirect indices such as… Expand
Solar modulation of cosmogenic nuclide production over the last millennium: comparison between 14C and 10Be records
For about the last 30 years it has been recognized that the high frequency component of the tree rings 14C/12C record is dominated by the modulation of the cosmic ray flux by the solar wind. In… Expand
Evolution of the Sun's large-scale magnetic field since the Maunder minimum
TLDR
A model describing the long-term evolution of the Sun's large-scale magnetic field reproduces the doubling of the interplanetary field and indicates that there is a direct connection between the length of the sunspot cycle and the secular variations. Expand
