| Abstract: | Electron radiation belts can change dramatically in a few seconds or slowly over years. Important issues in understanding such changes are: (1) What is the source of electrons in the radiation belts? (2) How important is radial diffusion compared to other radial transport mechanisms? (3) What are the detailed changes in the magnetosphere that produce radial diffusion? (4) Why is the response of the electron radiation belt to changes in the solar wind different from that of substorms and of the ring current? (5) Are processes other than radial transport, such as wave-particle interactions, important in energizing electrons in the radiation belts? |
