An assessment of the role of the centrifugal acceleration mechanism in high altitude polar cap oxygen ion outflow

The role of the centrifugal acceleration mechanism for ion outflow at high altitude above the polar cap has been investigated. Magnetometer data from the four Cluster spacecraft has been used to obtain an estimate of magnetic field gradients. This is combined with ion moment data of the convecti...
