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 …

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

Several models have been proposed for scaling in situ cosmogenic nuclide production rates
from the relatively few sites where they have been measured to other sites of interest. Two …

Direct observations of the geomagnetic field show that secular variation is strong in the
Atlantic hemisphere, and comparatively reduced in the Pacific region. The dipole has been …

We propose a new geomagnetic field model for the Holocene period based on
archaeomagnetic and lava flow data, avoiding the use of lake sediment data. The source of …

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 …

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 …

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

Thermal interactions between Earth's core and mantle provide the power that maintains the
geomagnetic field. However, the effect of these interactions and, in particular, the …

We present the results of full new calculation of radiocarbon 14C production in the Earth
atmosphere, using a numerical Monte-Carlo model. We provide, for the first time, a tabulated …
