Measurements of Atmospheric Electricity Aloft | SpringerLink

The sensor, known as the Balloon Electric Field Sensor (BEFS), consisted of a spherical superpressure balloon with a conductive coating on the outside—shown in Fig. 12b. The metal surface of the balloon was divided into sections, electrically separated from each other, which acted as the sensing electrodes, allowing determination of both horizontal and vertical components of the electric ...

A field mill for measuring atmospheric electricity

The charge sensor plate ... Figure 9 Trace showing the atmospheric electric field on a fine day. The PicoScope 5242A is ideal for data logging as the time scale can be set as long as 5000 seconds per division. Figure 9 shows a typical fine weather trace for about 5 mins: For the initial minute the rotating blade was covered with the tin lid and then it was uncovered for the rest of the time ...

A field mill for measuring atmospheric electricity

Thus, the field mill gives the earth’s electric field as 120 (±20) Vm^1 as the covered reading of approximately 50 mV is subtracted from the uncovered reading of 170 mV. Further measurements were made with the field mill on 22 June 2017. A thunderstorm had been forecast so there was a possibility of variability in the earth’s electric field.

Measurements of atmospheric electricity aloft

The Global Electric Circuit Early measurements of atmospheric electricity established the presence of a fair weather electric field, E, near the Earth’s surface which is typically 100 Vm1, in clear air conditions ( Scrase 1935)1. The direction of E is the direction in which a positive test charge moves under the influence
