Film the surface of the water to count raindrops. I assume this has been measured already, but don't have any sources... Does anyone know any? | |

| Jan 26, 2017 at 15:17 | comment | added | Felix Crazzolara | I'm not sure this is true, but I'm confused aswell. As far as I know earth has a charge of about -677kC and one can measure that on the earth surface we have a electric field of about 150 V/m direction to earth surface. So earth would be a negative point charge or at least, less positive than earth atmosphere? | |
| Jul 20, 2016 at 9:48 | comment | added | R. Rankin | Great answer! I just wanted to add that cosmic rays hitting the upper atmosphere cause showers of charged particles to rain towards earth. At sea level the most common of these is the muon. This mechanism would also serve to continuously charge the earth negatively, to what extent, I don't know. | |

Clear explanation. The charge unbalance of Earth (including atmosphere) is caused by the mass unbalance p/e.

I was completely wrong about the polarity. I've corrected it to the best of my knowledge now.
