Shannon information of the geomagnetic field for the past 7000 years [PDF]

Nonlinear Processes in Geophysics, 2010
The present behaviour of the geomagnetic field as expressed by the International Geomagnetic Reference Field (IGRF) deserves special attention when compared with that shown over the past few thousands of years by two paleomagnetic/archeomagnetic models ...

Comparison of IGRF models with North American Magnetic data.

Journal of geomagnetism and geoelectricity, 1982
Comparisons of proposed and adopted geomagnetic reference field models are made against North American test data for the period 1965 to 1985. These test data (X, Y, Z, and F) include Canadian map and aeromagnetic data and USGS land-based data. Model values are also tested against predicted component values for 1982 and 1984 derived from 27 magnetic ...

中国地区地磁场时空变化特征及模型精度评估

Dizhen xuebao
首先，基于第十三代国际地磁参考场（IGRF-13），以五年为时间间隔，对中国地区2000—2020年地磁场七个要素（X，Y，Z，H，D，I和F）的长期变化进行了系统的分析与探讨；其次，利用中国地磁台站的实际观测数据，研究了此期间地磁场逐年变化的特点，并以五年为间隔，探讨了1960—2020年中国地区内地磁场的变化模式；最后，通过分析IGRF-13和世界地磁模型WMM2020的计算结果与实际观测值之间的差值和均方根误差，深入探究了这些模型在中国地区的适用性差异。研究结果表明：2000—2020年间 ...

Recurrent neural network trained with the extended Kalman filter to forecast the geomagnetic secular variation for IGRF-14

Earth, Planets and Space
This study proposes a neural network approach for predicting the geomagnetic secular variation (SV) to improve the accuracy and efficiency of short-term geomagnetic forecasts. The International Geomagnetic Reference Field (IGRF), updated every five years,
