Fair weather electric field meter for atmospheric science ...
A miniature field meter is described for measuring fair weather electric fields (of magnitude ~100 Vm -1 ). It is a brushless field mill constructed from machine-cut parts, driven by a computer fan motor. It resolves fair weather fields at ~1 mV per (Vm −1 ), with a time response of 0.65 s. It implements self-calibration through combining a ...
