CT Russell is one of the partisan participants in the "Lightning Wars". At an LPSC around 1990 or a bit earlier, two participants in the wars were basically calling each other liars and data fudgers (I have no recollectin who they were, now). It's been one of the most heated, but least illuminated battles in planetary science over the years, fueled by a woeful lack of definitive data.

I think VExpress is repeating plasma wave radio emission measurements similar to those pioneer venus made over extended periods, but with a vastly better instrument. Cassini made similar measurements to VExpress, but over a brief flyby. This round goes to the radio emissions geeks.

HOWEVER... that they look like lightning created impulsive discharges doesn't prove they are. What we still need is a high sensitivity wide angle camera that can take airglow and surface-glow limited time exposures of the nightside, accumulating pole-to-pole, dawn-to-dusk coverate in broadband visible wavelengths, and at wavelengths that probe into the shortest wavelenfth infrared windows. Coupled with impulsive flash detectors, similar to those on lightning detectors in earth orbit, we could map the global time and space distribution of whatever lightning appears to be on the planet. Till we have such a map, or negative results from a high sensativity optical/ir lightning detector (meteor observation capable, too), I'm going to continue to be skeptical on this claim.

I'm not disputing their results, I've just watched this war too long.
