Users who have access to any one GIN can obtain worldwide geomagnetic data.
Access is free for purely academic use.
Rapid access to real-time data depends on rapid data acquisition. Participating observatories transmit data to a GIN within 72 hours. It is anticipated that within the next two years, more than 100 magnetic observatories will be participating. This holds definitive one-minute data from observatories participating in the project. The 1991 CD-ROM contains definitive data from 41 observatories.
