The INTERMAGNET data portal is hosted at the British Geological Survey (BGS). The service includes access to all INTERMAGNET provisonal and definitive data.

The data portal offers a number of services:

• A data visualisation and download web site: https://imag-data.bgs.ac.uk/GIN_V1/GINForms2
• A description of the INTERMAGNET data access web service: https://imag-data.bgs.ac.uk/GIN_V1/
• A HAPI web service interface to INTERMAGNET data: https://imag-data.bgs.ac.uk/GIN_V1/hapi. For information about HAPI see https://hapi-server.org/.
• Statistics on how data is used, how complete data provision is and the timeliness of data provided to INTERMAGNET: https://imag-data.bgs.ac.uk/GIN_V1/GINStatistics
• Access to data from observatories that are testing their data connection with INTERMAGNET (these data may not be observatory quality - you should check with the data provider before using these data): https://imag-data.bgs.ac.uk/GIN_V1/GINTest2
• An ftp service: imag-ftp.bgs.ac.uk

NOTE The ftp service will be discontinued at the start of March 2025. BGS are no longer able to continue the ftp service because of security requirements. Please use the other services listed on this page as an alternative.
