Overview
The center and the institute are now holding several types of geophysical data, including: geomagnetism data from 5 observatories, geomagnetic pulsation data from 3 stations, gravity data from stations in 10 provinces, and whistler data from 3 stations. The most geomagnetism data are analogue data, stored in magnetograms, except the data from Beijing Mingtomb Observatory (BMT) and Zhongshan Station, Antarctica are digitized and stored in disks or CD-ROMs. Other geophysical data are analogue and stored in magnetic tapes.
