A plasma density model for Saturn based on Voyager observationsThe present combination of ion and electron data sets from both Voyager flybys are to yield the broad view of the Saturn plasma environment indicates that a small, -10 to -20 V spacecraft potential furnishes a plausible basis for reconciliation of differences between observed ion and electron densities. A map of density contours within L = 12 is produced which incorporates all available Voyager thermal plasma data in this region, assuming that the inner mesosphere was stable during the nine months between encounters. The oxygen flux tube content decreases rapidly within L = 5, indicating the occurrence of losses in this region. Neural atom lifetimes in the inner magnetosphere lie in the range of weeks to years, and are a strong function of latitude.
