IMAGE has an "open access" policy, i.e. the final magnetometer data are freely available for scientific use. The institutes maintaining the network have invested a considerable amount of resources to provide high-quality data. Therefore it is important that these institutes have a measure of the scientific return on their investment. Accordingly, we ask that any publication or presentation making use of IMAGE data should include an acknowledgement statement such as (if data before 2014 is used):

"We thank the institutes who maintain the IMAGE Magnetometer Array: Tromsø Geophysical Observatory of UiT the Arctic University of Norway (Norway), Finnish Meteorological Institute (Finland), Institute of Geophysics Polish Academy of Sciences (Poland), GFZ German Research Centre for Geosciences (Germany), Geological Survey of Sweden (Sweden), Swedish Institute of Space Physics (Sweden), Sodankylä Geophysical Observatory of the University of Oulu (Finland), Polar Geophysical Institute (Russia), and DTU Technical University of Denmark (Denmark)."

Or (if only data after 2014 is used):

"We thank the institutes who maintain the IMAGE Magnetometer Array: Tromsø Geophysical Observatory of UiT the Arctic University of Norway (Norway), Finnish Meteorological Institute (Finland), Institute of Geophysics Polish Academy of Sciences (Poland), GFZ German Research Centre for Geosciences (Germany), Geological Survey of Sweden (Sweden), Swedish Institute of Space Physics (Sweden), Sodankylä Geophysical Observatory of the University of Oulu (Finland), and DTU Technical University of Denmark (Denmark)."
