| Research Abstract |
We have developed a data assimilation technique for incorporating in-situ data of the ring current plasma obtained by multiple spacecraft into a kinetic numerical simulation model. Under the conditions that the spacecraft are sufficiently distributed, general features in the distributions of plasma and electric potential are well reconstructed. We have also developed a data assimilation technique for modeling the plasmasphere using ultra-violet imaging data.
