Wouldn’t the tree explanation be refuted by simply recording the sounds in an open field, far away from trees?

  But what if the discharge requires some specific environmental factor, say, something the height of a tree?

    Maybe tree covered ground makes a more effective source of the rising-up component of this process. That relatively warm, negatively ionized rising air might be much diminished over a frozen lake or open plain. Otoh, it'd probably be greater over the ocean, I would think.

  Do people at Antarctic research stations ever hear this sound?

    Probably not as it requires a gradient, which that deserted and static landscape wouldn't provide.
