Optical Measurements of Sprites and Elves at StanfordEntry ID: ELVES_SPRITES_LIGHTNING
Abstract: Image and wave frequency data from Stanford led experiments concerning the lightning phenomena, Red Sprites and Elves, are available here.
"Elves" are transient luminous events in the lower ionosphere produced by nitrogen fluorescence due to electromagnetic pulses (EMPs) from intense return strokes of lightning discharges. The Fly's Eye is an array of photomultipier tubes designed to ... time-resolve the horizontal development of intense sub-millisecond ionospheric flashes that have come to be known as "elves". The Fly's Eye was built at Stanford University and deployed during the 1996 Sprites Campaign, and the data below were collected from Yucca Ridge Field Station near Fort Collins, Colorado, during July, 1996.
The Dobsonian Sprite Experiment uses a wide-field-of-view camera mounted on top of a telescope. Both the wide and narrow fields-of-view are recorded with image intensified CCD video cameras, with simultaneous recording of a broadband VLF crossed-loop antenna signal and GPS IRIG-B on the audio channels. Additionally a red-filtered Hamamatsu photomultiplier tube is mounted on top of the telescope and its signal is also recorded on an audio channel. The location is the terrace of the Langmuir Laboratory annex, located on the 11,000 ft high South Baldy peak, providing clear views of thunderstorms in Kansas, Colorado, Texas, and the north-west coast of Mexico.
