5.10.1 What is the temporal variability of 3D thermal particle distributions?

  • Burst mode resolution of EAS and PAS will provide fastest thermal distributions recorded at different radial distances in the solar wind. At high cadence, test:
  • how anisotropic and irregular are proton and electron distributions? This can test whether resonant heating or stochastic heating is the dominant heating mechanism.
  • how does the anisotropy change in time / space?
  • how are distributions related to local turbulence and global expansion? [multiple orbits, radial dependence] 



Required observations:


  • Long-term observations.
