For the global time stationary geomagnetic core field, a new modeling concept for Holocene archeomagnetic data is presented. Major challenges consist of the uneven data distribution, missing vector field components and non-linear relations between observations and the geomagnetic potential. Instead of a truncated spherical harmonics approach, we propose a fully Bayesian, Gaussian process based model. Inherently, the Bayesian approach provides location dependent uncertainties.

基于相关性的古地磁场快照模型

针对全球时间静止地磁核心场，提出了全新世古地磁数据建模的新概念。主要挑战包括数据分布不均匀、矢量场分量缺失以及观测值与地磁势之间的非线性关系。我们提出了一个完全基于贝叶斯、高斯过程的模型，而不是截断球谐函数方法。本质上，贝叶斯方法提供了位置相关的不确定性。
