IGGCAS Data service of Earth Science through Domestic and International Collaboration

Institute of Geology and Geophysics Chinese Academy of Sciences (IGGCAS) collects and archives data on Earth Science, and makes them available to the public. We focus on a continuous observations of earth's space environment for obtaining relevant space environment parameters on the geomagnetic field, electron density, wind field, temperature etc. in the upper atmosphere, ionosphere, magnetosphere. All the data has been collected through domestic collaboration over 40 sites. We also host the mirror site of the Madrigal (upper atmospheric science database from more than 100 sites) and DIDBase (over 80 ionosonde observatories).
