Resolution No.7 (1987): Continuous geomagnetic and ionospheric observations

IAGA, noting the high value which has to be given to long time series of geomagnetic and ionospheric observations, which have made great contributions to our present understanding of the Earth and its environment, recognising that in the current economic climate in many countries many such activities are being cut back and noting that particular examples of this are provided by the Witteveen Geomagnetic Observatory in the Netherlands, and by the long chain of ionospheric observatories which stretches from Raratonga, through New Zealand and Campbell Islands, to Scott Base in Antarctica, urges all member countries to maintain uninterrupted observations.
