N2 - Standing fast mode waves known as global modes, or cavity/waveguide modes, have been extensively studied as a potential driver of monochromatic shear Alfven waves in the Earth's magnetosphere via the field line resonance (FLR) mechanism. However, their existence outside of the plasmasphere remains controversial. We present here a global mode observation outside the plasmasphere, using simultaneous multispacecraft observations in the solar wind, the magnetosheath and the outer magnetosphere, as well as ground magnetometer data. Broadband solar wind dynamic pressure fluctuations are the most likely drivers of the Pc5 frequency range (2-7 mHz) global mode. The global mode transfers energy toward the plasmapause, where it drives localized shear Alfven wave activity in the Pc5 frequency range. Global modes are thus a viable mechanism for converting broadband energy sources to monochromatic, radially localized shear Alfven waves in the Pc5 frequency range.
