Really fascinating. After reading a little more, I learned that while Laine proposed the inversion layer hypothesis in 2016, the Auroral Acoustics group he headed was informally started in 2000. The reason the linked article is coming out now is due to Laine’s latest paper that details the triangulation of the sounds[1][2].
Would love to try and record this myself. I’ve been recording some VLF “sferics” for some time now for an art project[3]; it seems the auroral sound recordings often peak in the same frequency range (and perhaps there is overlap without me realizing it).
