Zusammenfassung |
Electricity in the atmosphere provides an ideal topic for educational
outreach in environmental science. To support this objective, a simple
instrument to measure real atmospheric electrical parameters has been
developed and its performance evaluated. This project compliments
educational activities undertaken by the Coupling of Atmospheric Layers
(CAL) European research collaboration. The new instrument is inexpensive to
construct and simple to operate, readily allowing it to be used in schools
as well as at the undergraduate University level. It is suited to students
at a variety of different educational levels, as the results can be analysed
with different levels of sophistication. Students can make measurements of
the fair weather electric field and current density, thereby gaining an
understanding of the electrical nature of the atmosphere. This work was
stimulated by the centenary of the 1906 paper in which C. T. R. Wilson
described a new apparatus to measure the electric field and conduction
current density. Measurements using instruments based on the same principles
continued regularly in the UK until 1979. The instrument proposed is based
on the same physical principles as C. T. R. Wilson's 1906 instrument. |
