AB: We are developing an inner magnetospheric electric field (UNH-IMEF) model at 2E so that the electric fields inside this radial distance are deduced from previously published results. The perigee is now precessing down to 3 R_E so that the database will be improved by using these Cluster data. Furthermore, the feature at 3-4 R_E is of interest because sub-auroral phenomena such as sub-auroral polarization streams are expected to be measured frequently. Ionospheric shielding of the magnetospheric electric field and ionospheric dynamo effects would be measured. Second topic of interest is the improvement of the database by introducing the moment data from CIS instrument. This instrument measures bulk velocity during injection events, which tends to be missed by EDI. We will consider the possible improvement of our model from the above data newly introduced.
