We compare the expected signature of the inflow region of the proposed corotating convection pattern with relevant magnetic field and plasma flow observations made by Pioneers 10 and 11 and Voyagers 1 and 2 in the Jovian magnetosphere (r>10RJ). A region ofnet plasma in flow would be characterized by superrotation and a negative radial current in the equatorial plane within a chracteristic distance L*. We find that no value of L* exists that is consistent with both plasma and magnetic field observations. Hence we conclude that at the time of these flybys, such a simple large-scale convection pattern did not dominate the plasma transport in the outer magnetosphere, although the existence of such a pattern in the inner magnetosphere is not ruled out. We propose a more detailed test to determine whether or not a supersposition of corotating convection and radial diffusion is consistent with the observations.
