Resolution No.4 (1987): Continuous measurement of solar wind parameters

IAGA, recognising the importance of the interplanetary magnetic field and plasma field and plasma parameters which are fundamental for energy input into the magnetosphere and provide the driving energy for many of the phenomena studied by IAGA scientists, recommends to the countries engaged in space experiments that efforts be made to assure the continuous measurements of the interplanetary magnetic field and plasma parameters and the timely dissemination of these data on a world-wide basis.
