Presented here is 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. The …

The brightness of the Sun varies on all timescales on which it has been observed, and there
is increasing evidence that this has an influence on climate. The amplitudes of such …

Understanding the temporal variation of cosmic radiation and solar activity during the
Holocene is essential for studies of the solar-terrestrial relationship. Cosmic-ray produced …

Reconstructions of the Holocene geomagnetic field and how it varies on millennial
timescales are important for understanding processes in the core but may also be used to …

Context. Long-term records of solar radiative output are vital for understanding solar
variability and past climate change. Measurements of solar irradiance are available for only …

Aims. Cosmogenic isotopes provide the only quantitative proxy for analyzing the long-term
solar variability over a centennial timescale. While essential progress has been achieved in …

Steadily increasing numbers of archeomagnetic and paleomagnetic data for the Holocene
have allowed development of temporally continuous global spherical harmonic models of …

Background GEOMAGIA50. v3 is a comprehensive online database providing access to
published paleomagnetic, rock magnetic, and chronological data from a variety of materials …

Paleomagnetic records from sediments, archeological artifacts, and lava flows provide the
foundation for studying geomagnetic field changes over 0–100 ka. Late Quaternary time …

The Sun is magnetically active and often produces eruptive events on different energetic
and temporal scales. Until recently, the upper limit of such events was unknown and …
