Determining lightning polarity (positive or negative) by raw signal processing?
#19
Assuming  the magenta channel is the E field and the yellow one the H field, this is my tentative identification:

Positive query huh
unclear -CG
unclear -CG
+CG     -CG
-CG ??  -CG
unclear +CG
-CG      -CG

positive query huh2
+CG    +CG
unclear -CG
+CG    +CG
-CG     +CG
unclear unclear
unclear +CG

I used the polarity of the first part of the E field signal, when I could identify the start. When the first pulse of the E field is positive I identify it as -CG, when it goes negative as +CG. This is then in line with the signal I presented above.
I would have prefered to see the horizontal H signals as well to get a better idea of the start, the signal of the  C channel is a bit weak.
