Stanford University ELF/VLF DataEntry ID: STANFORD_VLF
Abstract: The Stanford VLF Group collects data from ground stations located across the globe. There are two principle types of data collected, broadband and narrowband. Broadband data is full waveform data sampled at 100 kHz (frequency range of 300 Hz to 40 kHz). Narrowband data refers to the demodulated amplitude and phase of narrowband VLF transmitters. Both broadband and narrowband data is typically collected on two orthogonal antennas oriented in the North/South and East/West directions. Data availability charts, data summary charts, raw data, and tools for reading and plotting the data are available.
Purpose: The Stanford University VLF Group investigates the Earth's electrical environment, its upper atmosphere, lightning discharges, radiation belts, and the ionized regions of the earth's upper atmosphere known as the ionosphere and magnetosphere. Much of our work involves the use of very low frequency (VLF) electromagnetic waves which are generated by lightning discharges, by man-made transmitters and by the energetic radiation belt electrons. We use VLF waves as diagnostic tools to investigate physical processes in the vicinity of the Earth's low and high altitude plasma environment. Under the direction of Professor Umran Inan, the VLF group carries out extensive observational programs at multiple sites across the world on all seven continents.
