Data assimilation in geomagnetism designates the set of inverse methods for geomagnetic
data analysis which rely on an underlying prognostic numerical model of core dynamics …

This paper reviews the remarkable developments in numerical geodynamo simulations over
the last few years. Simulations with Ekman numbers as low as E= 10− 8 E= 10− 8 are now …

This volume is a major revision and expansion of Taylor's seminal book Radiocarbon
Dating: An Archaeological Perspective. It covers the major advances and accomplishments …

For many published dynamo models an Earth-like magnetic field has been claimed.
However, it has also been noted that as the Ekman number (viscosity) is lowered to less …

The state of knowledge and understanding of planetary magnetic fields is reviewed. All of
the planets, with the possible exception of Venus, have had active dynamos at some time in …

The variable magnetic field of the solar photosphere exhibits periodic reversals as a result of
dynamo activity occurring within the solar interior. We decompose the surface field as …

We introduce ensembles of time-varying archeomagnetic field models, consisting of a
reference model, a mean model and a thousand individual models. We present a set of …

This paper presents a new covert channel using smartphone magnetic sensors. We show
that modern smartphones are capable to detect the magnetic field changes induced by …

As the Earths surface deviates from its spherical shape by less than 0.4 percent of its radius
and today's satellite missions collect their gravitational and magnetic data on nearly …

Geomagnetic dipole moment variations associated with polarity reversals and excursions
are expressed by large changes of the cosmogenic nuclide beryllium‐10 (10Be) production …
