Resolution No.13 (1991): Real-time monitoring of the solar wind

IAGA noting that advanced technological systems (especially electric power distribution and radio communications) are increasingly sensitive to natural variations in the Earth's magnetic field, magnetosphere and ionosphere, and noting that considerable progress has been made in quantitative understanding of the physical relations between solar wind parameters and the responses in geophysical parameters, recommends that the solar wind plasma and interplanetary magnetic field parameters be monitored upstream of the Earth in near real-time, and that the data be distributed internationally to anticipate possible terrestrial responses to severe solar wind fluctuations.
