Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement
Geophysical Monograph Series, Page 27-82., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Geomagnetic main field modeling with DMSP [PDF]
Journal of Geophysical Research: Space Physics, 2014 AbstractThe Defense Meteorological Satellite Program (DMSP) launches and maintains a network of satellites to monitor the meteorological, oceanographic, and solar‐terrestrial physics environments. In the past decade, geomagnetic field modelers have focused much attention on magnetic measurements from missions such as CHAMP, Ørsted, and SAC‐C.

An improved geomagnetic data selection algorithm for global geomagnetic field modelling [PDF]
Geophysical Journal International, 2007 A spherical harmonic degrees 60, global internal field model is described (called BGS/G/L/0706). This model includes a degree 15 core and piecewise-linear secular variation model and is derived from quiet-time Orsted and CHAMP satellite data sampled between 2001.0 and 2005.0.

The development of a regional geomagnetic daily variation model using neural networks [PDF]
Annales Geophysicae, 2000 Global and regional geomagnetic field models give the components of the geomagnetic field as functions of position and epoch; most utilise a polynomial or Fourier series to map the input variables to the geomagnetic field values.

Recovering external contribution from the monthly mean series of a given geomagnetic observatory
Annals of Geophysics, 2016 The differences between monthly mean values of the observed geomagnetic field and monthly values predicted by different models of the internal geomagnetic field (named “model biases”) for the time period 2000-2015 at several geomagnetic observatories are

Can core-surface flow models be used to improve the forecast of the Earth's main magnetic field? [PDF]
, 2008 [1] Geomagnetic main field models used for navigation are updated every 5 years and contain a forecast of the geomagnetic secular variation for the upcoming epoch. Forecasting secular variation is a difficult task.

Geomagnetic Core Field Secular Variation Models
Space Science Reviews, 2009 We analyse models describing time changes of the Earth’s core magnetic field (secular variation) covering the historical period (several centuries) and the more recent satellite era (previous decade), and we illustrate how both the information contained in the data and the a priori information (regularisation) affect the result of the ill-posed ...
