Conference Objective

The purpose of this proposed Chapman Conference is to bring together scientists working in experiments, data analysis, and theory, on the excitation mechanism and propagation mode of magnetospheric ULF waves, the interaction of the waves with the magnetospheric plasma and energetic particles, and magnetospheric diagnostics using the waves.

Conference Overview

Listed below are general topics that will be the main focus of this conference.

• Excitation and Propagation: ULF waves are excited through a variety of mechanisms including direct solar wind interaction with the magnetosphere, substorm processes in the magnetotail, and kinetic instabilities in the inner magnetosphere. As the waves propagate over large distances the excitation region and energy dissipation region can be quite distant. In addition, mode coupling and the driving of secondary modes through modification of the equilibrium can occur. These characteristics pose a significant challenge to the overall understanding of the global transport processes involving ULF waves.
• Interaction with Plasma and Energetic Particles: Once excited, the waves interact with surrounding plasma and energetic particles and modify their properties. The regulation of temperature anisotropy by ion cyclotron and mirror waves is an example of such a process. Drift bounce resonant or drift-mirror kinetic instabilities probably regulate the pressure gradient and/or plasma beta. ULF waves are known to have an important effect in energizing radiation belt particles, and they may have an important role in substorm onset and reconnection.
• Magnetospheric Diagnostics: In the past decade numerous spacecraft have observed ULF waves, novel techniques were developed in data analysis, and new active and passive ground-based experiments were deployed to detect ULF waves and to use them as a tool to probe the geospace. For instance, the equatorial mass density, which is otherwise difficult to measure, can be inferred from the frequencies of toroidal Alfvén waves.
• Since the last major conference on ULF waves (Williamsburg, 1992), there have been many developments that make a new examination of ULF waves timely. First, new spacecraft have given us new views of the waves and associated plasma. For instance, using spacecraft with polar orbits, the Poynting vector associated with ULF waves has been measured at various latitudes, leading to insights on their source and energy flow; recent observations measured by the multiple spacecraft of Cluster II have been used to determine unambiguously wave vectors. On the ground, magnetometer arrays and radar networks have enormously expanded to detect ULF signals on a global scale with high timing accuracy. Numerical simulations of ULF waves have become increasingly powerful, especially with their ability to incorporate realistic boundary conditions and magnetospheric configurations. Finally, the significance of ULF waves for space weather, as demonstrated by their effect on energetic particles, has only recently been appreciated. With space weather programs gaining momentum and new multispacecraft programs under way, now is a good time to assess the progress of ULF waves and identify focus areas for future research that are relevant to these programs.
