Ramon - atmospheric electric potential gradient
Potential gradient is measured using a CS110 electric-field mill. It is mounted on a 3m metal tripod, fixed to the ground. The surface is mostly sedimentary rocks and some loose dust. It is situated far from the main observatory dome (100 m).
The instrument is located at 875 m a.s.l.
Measurement frequency is 1Hz
This is used in the Glocaem potential gradient network
