DMSP energy and energy flux, May 19, 1996



The top figure shows the energy flux measured by DMSP along a track across the auroral zone (solid lines), and the energy flux derived from the UVI images along that track (symbols). The two solid lines from the DMSP data show the energy flux under the assumption of isotropic flux (lower line) and field aligned flux (upper line). The bottom panel shows the characteristic energy. The characteristic energy is derived from the brightness ratio of the LBH-short to LBH-long images (symbols). The solid line represents the in situ DMSP observations. (G. Germany)
