中国区域Dst指数数据集(2010-2022)
A dataset of Dst Indexes in China(2010-2022)
摘要
Abstract
The axisymmetric disturbance of the Geomagnetic field caused by the ring current can be quantified using the Disturbance storm-time(Dst)index.Due to the asymmetry of the ring current during the storm time,there are s notable variations in the geomagnetic disturbance levels at different locations,which cannot be accurately reflected by the globally averaged Dst index.In this paper,we collected and calculated the geomagnetic data of the Chinese Meridian Project in Lasa,Chengdu,Wuhan and Hangzhou,so as to produce a dataset of Dst Indexes in China.This dataset includes Chinese Dst indexes from 2010 to 2022,with a total of 109,608 entries of data.In addition to the comprehensive collection of Dst indexes,this dataset can be used to better describe the geomagnetic disturbances in the Chinese region and is expected to furnish valuable data for regional space weather research in China.关键词
