Resolution No.4 (2009): Geomagnetic Observatories

IAGA, recognising

• the importance of long time series of high quality geomagnetic observatory observations in characterizing the geomagnetic field,
• the combination of a global geomagnetic observatory network and modern satellite missions in optimizing progress in geomagnetism science, including greater understanding of the 'Earth system' and more accurate mapping and prediction of geomagnetic field changes and space weather conditions,

notes that many geomagnetic observatories continue to have uncertain futures, and therefore urges national agencies to ensure the continued operation of magnetic observatories during the lifetime of the ESA Swarm satellite mission and beyond.
