INTERMAGNET data are available as magnetograms or as digital data files. Policies and procedures for making this data available are the responsibility of each GIN.
Geomagnetic data can be downloaded via your browser. The availability of data files is dependant on the publishing delay of participating institutes. Pre-INTERMAGNET data may be available via on of the World Data Centres (WDC) or the observatory contact of the specific Magnetic Observatories (IMOs).
Geomagnetic data can also be downloaded via the INTERMAGNET FTP. A user account is required to access to this data. To request this service, please send an e-mail to: NRCan.geomag-webmaster-geomag-webmaster.RNCan@canada.ca.
Plots can be generated for all INTERMAGNET data available through this web site.
Conditions of Use
The member institutes of INTERMAGNET invest considerable resources to operate their magnetic observatories to INTERMAGNET standards. It is important that the institutes producing the data have a measure of the scientific return on their investment. Accordingly, we have the following Conditions of Use.
Conditions of Use for data provided through INTERMAGNET
The data made available through INTERMAGNET are provided for your use and are not for commercial use or sale or distribution to third parties without the written permission of the institute operating the observatory. Publications making use of the data should include an acknowledgment statement of the form given below. A citation reference should be sent to the INTERMAGNET Secretary (email@example.com) for inclusion in a publications list on the INTERMAGNET website.
Acknowledgement of data from observatories participating in INTERMAGNET
We offer two acknowledgement templates. The first is for cases where data from many observatories have been used and it is not practical to list them all, or each of their operating institutes. The second is for cases where research results have been produced using a smaller set of observatories.
Suggested Acknowledgement Text (template 1)
The results presented in this paper rely on data collected at magnetic observatories. We thank the national institutes that support them and INTERMAGNET for promoting high standards of magnetic observatory practice (www.intermagnet.org).
Suggested Acknowledgement Text (template 2)
The results presented in this paper rely on the data collected at observatory name. We thank institute name, for supporting its operation and INTERMAGNET for promoting high standards of magnetic observatory practice (www.intermagnet.org).
