We investigate the occurrence characteristics and amplitude-frequency relationships of Pc5 ultra-low frequency (ULF) waves (1.67–6.7 mHz) using 30 years of GOES magnetic field data (1995–2025) from GOES-8 to GOES-18. An enhanced CLEAN algorithm, employing iterative Hanning peak model fitting and subtraction, identified 27,279 radial, 26,145 azimuthal, and 31,259 parallel wave events in the Mean Field-Aligned coordinate system. Radial and parallel waves exhibit peak amplitudes between 9–15 MLT, driven by solar wind dynamic pressure, while azimuthal and parallel components dominate in the 15–21 MLT sector, consistent with Kelvin-Helmholtz instability.
