Description/Abstract
The work considers the scattering of sub-ionospheric VLF radiation by by vertical plasma columns of sprites. Sprites are cloud to ionosphere discharges. Using a Born 3D VLF wave scattering code we have computed the VLF perturbations or 'Trimpis' resulting from scattering from the sprite plasma columns. COmparison with field observations of forward and back scatter amplitudes it is shown that the minimum electron density in the columns must be of order 10**10 el/cubic metre at 70km, in contrast to the calculations of the Stanford group.
