A Multi-Point Perspective on the Solar Wind at a Small Scale

While a broad-brush picture of the heliosphere is typically available for space weather prediction, key parameters can change significantly over a million-kilometer scale. In this presentation, I will discuss the importance of energetic particle predictions for space weather and delve into recent energetic particle transport modeling work which may substantially improve available predictions. Using joint data from the ACE, Wind and STEREO spacecraft, I will explore the limitations on these predictions created by sharp gradients in the energetic particle intensity. I will present the physical properties of these gradients and their relationship to both large-scale solar wind structures and turbulence.
