Evolution of the solar irradiance during the Holocene [PDF]
, 2011 Aims. We present a physically consistent reconstruction of the total solar irradiance for the Holocene. Methods. We extend the SATIRE models to estimate the evolution of the total (and partly spectral) solar irradiance over the Holocene.

Geomagnetism : review 2010 [PDF]
, 2011 The Geomagnetism team measures, records, models and interprets variations in the Earth’s natural magnetic fields, across the world and over time. Our data and expertise help to develop scientific understanding of the evolution of the solid Earth and ...

MoSST DAS: The First Working Geomagnetic Data Assimilation System [PDF]
, 2011 The Earth possesses an internal magnetic field (geomagnetic field) generated by convection in the outer core (geodynamo). Previous efforts have been focused along two distinct paths: (1) numerical geodynamo modeling to understand the origin of the ...

Influence of different data selection criteria on internal geomagnetic field modeling
Earth and Planetary PhysicsEarth’s internal core and crustal magnetic fields, as measured by geomagnetic satellites like MSS-1 (Macau Science Satellite-1) and Swarm, are vital for understanding core dynamics and tectonic evolution.

The use of geomagnetic field models in magnetic surveys [PDF]
The importance of global geomagnetic field models for the reduction of magnetic surveys is discussed. It is demonstrated that a numerical model with adequate secular variation correction, provides a suitable representation of the regional field.

Data use investigation for the magnetic field satellite (MAGSAT) mission: Geomagnetic field forecasting and fluid dynamics of the core [PDF]
MAGSAT data were used to construct a variety of spherical harmonic models of the main geomagnetic field emanating from Earth's liquid core at poch 1980. These models were used to: (1) accurately determine the radius of Earth's core by a magnetic method, (

Geomagnetic Core Field Models in the Satellite Era
, 2010 After a brief review of the theoretical basis and difficulties that modelers are facing, we present three recent models of the geomagnetic field originating in the Earth’s core. All three modeling approaches are using recent observatory and near-Earth orbiting survey satellite data. In each case the specific aims and techniques used by the modelers are

Does the current minimum validate (or invalidate) cycle prediction methods? [PDF]
, 2010 This deep, extended solar minimum and the slow start to Cycle 24 strongly suggest that Cycle 24 will be a small cycle. A wide array of solar cycle prediction techniques have been applied to predicting the amplitude of Cycle 24 with widely different ...

What happens when the geomagnetic field reverses?
, 2012 During geomagnetic field reversals the radiation belt high-energy proton populations become depleted. Their energy spectra become softer, with the trapped particles of highest energies being lost first, and eventually recovering after a field reversal ...
