The Schumann resonance on Venus

Venus has an extremely dense atmosphere composed predominantly of carbon dioxide and a permanent ionosphere, so in principle it is a suitable candidate for its own cavity resonator. The question of whether lightning activity capable of exciting the SR occurs on Venus has long been debated; the resonance itself has not yet been measured directly.

The parameters of a Venusian SR were modeled by a three-dimensional FDTD simulation together with Mars and Titan Yang 2006. The dense atmosphere and a conductivity profile different from Earth's lead in the models to different values of the resonance frequencies and damping than on Earth. As with Mars, however, these so far remain purely modeled predictions: no in-situ ELF measurement that would confirm a Venusian SR is available.
