<p> Very Low Frequency (VLF 3-30 kHz) receivers are used to monitor the amplitude and phase of signals from powerful naval VLF communication transmitters. Since the VLF transmitter signals propagate in the Earth-ionosphere waveguide, they provide a method for remotely sensing ionospheric density changes. The effect of powerful natural oceanic lighting discharges on the ionosphere are investigated using VLF remote sensing and the Global Lighting Detection Network (GLD360). Ionospheric disturbances known as Lighting-induced Electron Precipitation (LEP) events and Early/Fast events are investigated. A comprehensive numerical model of the electron precipitation process is used to compare to observation. Results are compared to previous research on lightning effects on the ionosphere. </p>
