A Systematic Look at the Temperature Gradient Contribution to the Dayside Magnetopause Current

Magnetopause diamagnetic currents arise from density and temperature driven pressure gradients across the boundary layer. While theoretically recognized, contributions to magnetopause current system have not yet been systematically studied. To bridge this gap, we used a database of Magnetospheric Multiscale (MMS) crossings analyze densities their dayside flank magnetopause. Our results indicate that ion gradient component makes up 37% along typically opposes classical Chapman-Ferraro direction, interfering destructively with component, thus lowering total density. This effect is most pronounced on The electron was found be 5 14 times weaker than average.
