Correlation between meteors and VLF-ELF signals ?

As described in the publication at the link :
http://air-radiorama.blogspot.it/2014/02/meteor-counter-with-graves-radar.html
in cooperation with many people , and in particular with Paul Nicholson , after months of automatic collection of relevant selected time stamped events ,we have enough material for who would like to develop a study around .
The data of more than 40 days (538 Mb) with 1059 events are available as images at the link :
ftp://sidmonitor.for-more.biz/0zipped%20archive/

There are four images for each event :



 1) Raw spectrogram of the echo of the meteor

2) Time domain GPS time stamped and correlated strip chart of :

A) The demodulated meteor echo ( "ping" ) in CW in Turin - Italy 
B) The VLF survey in Cumiana-Italy
C) The VLF survey in Bielefeld -Germany

Peaks in B and C are typically supposed to be lightning strikes 


3) Echo spectrogram expanded in time for VHF and VLF-ELF with pallette for amplitude


4) Echo spectrogram expanded in time for VHF and VLF-ELF with pallette for amplitude with only two colours
