I'm only an aspiring physicist, but it seems like the arxiv article assumes an external magnetic field. This could explain why the author only mentions altitude change in satellites.
In Sweden we have a semi-public infrasound network that could detect civilian supersonic flights across the atlantic. It is used for nuclear weapons controll. Since several of the sources is public (but not those under control of the UN), media should be able to pinpoint any peculiar large explosions at that relevant time.
I'm not entirely sure of the range, but the system can detect and pin-point Russian SSBM launches. The relevant link is http://www.umea.irf.se/. During the first North Korean nuclear crisis Swedish intelligence quickly knew what was going on. The instrument used for finding trace isotopes in the air was also Swedish.
I have some memory of a really useful but delayed data source from this network. With it you could "hear" the workshifts in mines, accelerations from Concorde aircrafts etc. But I don't remember the link. Does anyone remember it?
