Resolution No. 3 (2011): Dst observatories

IAGA, noting the importance of the Dst index for various applications including geomagnetic field modeling, space-weather and -climate studies and detection of local anomalous variations, recognizing that the absolute accuracy of the data from the contributing observatories, Kakioka, Honolulu, San Juan, Hermanus and Alibag, is essential, recommends that all agencies operating these geomagnetic observatories continue to support both absolute and variation measurements to maintain the required level of accuracy.
