Amplitudes and fraction of power of LWs in the solar wind associated with different source regions. (a) TSWF data of the maximum amplitude (E_max) of solar wind LWs (black), LWs associated with RBs (green), and LWs associated with MHs (red). E_max corresponds to the highest electric field measurement value of a snapshot. (b) STAT data of the maximum amplitude (E_max) of solar wind LWs (black), LWs associated with RBs (green), and LWs associated with MHs (red). E_max corresponds to the highest amplitude of all the snapshots containing LWs in a STAT packet. (c) Fraction of power of the TSWF solar wind LW (black), RB LWs (green), and MH LWs (red).
