地磁Kp数据(1932~2016)

本数据是美国地球物理数据中心（NGDC）提供的1932-2013年间的地磁三小时Kp指数数据，由全球不同纬度的13个台站（此处为磁纬北纬46~南纬63度的Lerwick等13个台站）K指数的平均，K指数是由单台站三小时地磁H分量（或者D分量）在减去太阳日变化Sq和太阴日变化L后的纯磁扰曲线最高值和最低值来确定的,根据磁扰强度分为0～9的10等级。行星Kp指数是一种衡量全球性地磁变化的指数。

This dataset contains 3-hourly geomagnetic Kp index data from 1932 to 2013, provided by the National Geophysical Data Center (NGDC). The Kp index is calculated as the average of K indices from 13 global observatories spanning various latitudes, including stations such as Lerwick with magnetic latitudes ranging from 46°N to 63°S. The K index for a single observatory is determined by the maximum and minimum values of the pure magnetic disturbance curve, which is derived by subtracting the solar daily variation (Sq) and lunar daily variation (L) from the 3-hourly geomagnetic H-component (or D-component) of that station. It is classified into 10 levels from 0 to 9 based on the intensity of magnetic disturbances. The planetary Kp index is an indicator used to measure global geomagnetic variations.
