A Dataset of Kp index in the Chines Region (2022-2024)

In 2011, the National Space Science Center of the Chinese Academy of Sciences established the Chinese Academy of Sciences Space Environment Monitoring Network. Currently, its geomagnetic observatory stations include those in Mohe, Beijing, Langfang, Sanya, and Fuke. By integrating and processing the H-component monitoring data from fluxgate magnetometers at these five geomagnetic observatory stations, we have developed a geomagnetic Kp index that can effectively identify the day-to-day variation characteristics of the geomagnetic regular daily variation, reflect the seasonal and local time effects of geomagnetic disturbances, and is suitable for the distribution characteristics of China's geomagnetic observatory network. This dataset contains the geomagnetic Kp indices for the five geomagnetic observatory stations from 2022 to 2024. It addresses the current situation where the official Kp index is released with a two-week delay, failing to meet operational requirements, and can better describe geomagnetic disturbances in the Chinese region. It is expected to provide data support for space weather research in the Chinese region.
