Conditions of use
The Geomagnetic data available through this site are provided for your use (and for the use of colleagues collaborating on the same project) and are not for sale or distribution by you to third parties, without the express written permission of the Geological Survey of Canada (GSC). Any report or publication that makes use of these data should acknowledge the Geological Survey of Canada as the source. One copy of each report or publication should be sent to the GSC.
We ask that the data not be used for commercial purposes, nor in any project in which you, your organization, or your collaborators are in a commercial agreement with any third party. Commercial users should contact Geomagnetism-Info@NRCan-RNCan.gc.ca.
Your e-mail address, which you provide when requesting data, will be used so that the GSC may monitor the use of its data.
By accessing these data you signify your acceptance of these terms and conditions.
Please note that there are spikes and offsets in some of the definitive data before 1992 which could have an impact on research results especially extreme event studies. It is advised to perform quality checks on the data and inter-comparisons between observatories to confirm all identified extreme events. It should also be noted that over time various magnetometer systems have been used to collect the data and the filtering to create the 1-minute data has changed. We are working towards correcting this matter.
