Goal: Understand the interactions between intermediate frequency waves and plasma species as they co-evolve and stream away from the Sun, and how they interact with or are driven by macroscale solar wind structures.

Science questions 1.) What is the interdependence between intermediate frequency waves and large-scale structures, including interplanetary shocks and stream interaction regions, and does it depend on distance from the Sun? 2.) How do the occurrence, properties, and dominant instability mechanisms of intermediate frequency waves depend on distance from the Sun? 3.) How do the changes in dominant wave modes impact the evolution of electrons and ions? 4.) Near 1 AU, how do these waves depend on solar cycle?
