2010.0年代中国地磁参考场-磁倾角I空间分布等值线

根据“2010.0中国地区地磁场8阶球冠谐模型”、在北纬0°～54°、东经73°～136°的空间范围内，以1°×1°的空间密度计算获得《“2010.0中国地区地磁场8阶球冠谐模型”输出点阵-I要素》。
2010年10月，经中国地震局地球物理研究所组织了由中国科学院地质与地球物理研究所、中国地质大学（北京）、云南大学、《地球物理学报》编辑部以及中国地震局系统的专家，在北京召开了专题学术会议，对该模型的研究过程和最终结果进行了评审和确认。
使用surfer7.0绘图软件，根据《“2010.0中国地区地磁场8阶球冠谐模型”输出点阵-I要素》绘制而成。蓝色线条为I要素-负异常的空间分布等值线，红色线条为I要素-正异常的空间分布等值线，黑色线条为I要素-零异常的空间分布等值线。等间距为1′。
用于描述2010.0年代中国及周边地区地磁参考场I要素的空间分布，是2010.0年代该地区国家级、权威的区域地磁参考场。

Based on the "2010.0 8th-order Spherical Cap Harmonic Model of Geomagnetic Field over China", the "2010.0 8th-order Spherical Cap Harmonic Model of Geomagnetic Field over China" Output Grid Points - I Component was calculated within the spatial domain of 0°–54°N latitude and 73°–136°E longitude at a spatial resolution of 1°×1°.

In October 2010, the Institute of Geophysics of the China Earthquake Administration organized a special academic conference in Beijing, with experts from the Institute of Geology and Geophysics of the Chinese Academy of Sciences, China University of Geosciences (Beijing), Yunnan University, the Editorial Office of *Acta Geophysica Sinica*, and the China Earthquake Administration system, to review and confirm the research process and final results of this model.

The map was plotted using Surfer 7.0 software based on the "2010.0 8th-order Spherical Cap Harmonic Model of Geomagnetic Field over China" Output Grid Points - I Component. Blue lines represent the spatial distribution contour lines of negative anomalies of the I component, red lines represent the spatial distribution contour lines of positive anomalies of the I component, and black lines represent the spatial distribution contour lines of zero anomalies of the I component. The contour interval is 1 arcminute.

This dataset is used to describe the spatial distribution of the I component of the geomagnetic reference field over China and its surrounding areas in the 2010.0 epoch, and it is a national-level and authoritative regional geomagnetic reference field for this region in the 2010.0 epoch.
