Abstract : This report is a summary of disturbance effects of three major energetic particle events (PCA's) on VLF/LF propagation parameters as observed by the Phillips Laboratory High Resolution Oblique VLF/LF Ionosounder located in northern Greenland. Disturbance effects on ionospheric reflectivity parameters, including deduced reflection heights and plane wave reflection coefficients, are presented along with riometer, magnetometer, and satellite particle detector data.
