Minimum Sprite Plasma Density as Determined by VLF Scattering

Dowden, RL, Rodger, CJ and Nunn, D (2001) Minimum Sprite Plasma Density as Determined by VLF Scattering IEEE Antennas and Propagation Magazine, 43, (2), pp. 12-24.

Record type: Article


This work considers the scattering of subionospheric VLF radiation by sprite plasma columns.We run a three dimensional simulation model based upon the linear Born approximation. Calculations show that to agree with observed VLF forward and back scattering, the plasma density in the sprite columns must be about 100000/cc at a height of 55km and 10**10/ cubic metre at 70km. By contrast the early/fast events as defined by the Stanford group do not exhibit scatter angles above 15 degrees, suggesting that sprite conductivity rises too slowly (as the plasma cools) to reach adequate backscatter within the time allowed by the early/fast definition
