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