The space weather effects at the Earth’s magnetosphere are mostly driven by the solar wind that carries the Interplanetary Magnetic Field (IMF). The incoming solar wind properties at Lagrange point 1 (L1) are typically used for developing various space weather forecasts. In this presentation we use several years of data in the solar wind from ACE and Wind spacecraft located at L1, ARTEMIS spacecraft orbiting the moon, and MMS spacecraft upstream of Earth’s bow shock, to study the multi-scale structure of the IMF. Wavelet transform analysis and information theory analysis of the magnetic field data of the three locations were examined and compared. The aim of this research is to improve our understanding of the evolution and dissipation of different scale-size solar wind magnetic structures as they move from L1 to Earth’s bow shock, and ultimately, improve space weather forecasting methods.
