Reply [to “Comment on ‘Is Venus alive?’”]



In his comment, Frederick Scarf asserts that many statements and interpretations contained in my Forum are wrong and that he proposes to correct the record. The opposite is in fact the case, and his response adds no substantiation to the claim that there is extensive lightning and currently active volcanism at Venus.

My colleagues and I have shown (H. A. Taylor, Jr., et al., “Reply,” Journal of Geophysical Research, vol. 91, p. 4599, 1986) that there is a high degree of correlation between the electric field noise and the ionospheric disturbances driven by the solar wind—ionosphere interaction and that the noise is not preferentially clustered over mountainous terrain. These results run counter to the interpretation of the noise as evidence of lightning and I stand on this evidence.
