Just to make it clear for those who don't know radio scattering methods,
these are recordings not of the sound the meteors make when entering the
atmosphere (they don't seem to make much sound at all, radio or aural), but
the sounds of over-the-horizon FM radio stations that reflect off the
ionized trail in the wake of a meteors passage and become audible for a ver=
y
short time, the duration of the ionized trail.
They aren't strictly nature recordings, but they are very interesting. I
tried this with the most recent Leonids but didn't hear anything in Utah. I
think I should have used a more directional antenna.

Subject: [Nature Recordists] The nature recording of meteor storms
Greetings Nature Recordists.
Part of my Science practice is the observation and audio recording of
fireballs, space dust and meteor phenomena. I operate the Radio Fireball
Observatory in north central New Mexico, US.
I thought some of you might be interested in the audio of a couple of
great and historic meteor storms as recorded by the forward scatter
method. I made a webpage of some specimen fireball reflections and
added two half hour long recordings of the peaks of the 2001 Leonid storms.
The forward scatter method is a little too complex to explain here but I
posted links to information on the webpage.
