If new formats are developed, tools for data base conversion should be developed as well. Downloading data sets over the WWW may be too slow, so that distribution on CD-ROM or other media will remain necessary. It should be possible to update archived data sets. The need for early access to data before the certified data are available is restated. Interaction with equatorial ionospheric jets should be considered with diffusion.
Solar activity changes the diffusion coefficients.
Tverskaya asks for more observations of the influence of substorms. S. Huston asks which processes should have priority in the modelling process. A discussion on the needs for empirical and theoretical models ensues, as well as on the purposes of the models. The end users and their needs should be defined. It is suggested to use Garrett's review as a guideline.
