Question

electrical conductivity of ionosphere is​

Answer 1

Answer:

Introduction

The ionosphere is the region where plasma density is maximum in the Earth's upper atmosphere. Its altitude ranges almost from 60 to 1000 km. It acts not only as the reflection or absorption layer of the radio wave, but as an electric current layer. The ionospheric currents cause large part of the variation of the geomagnetic field, although most of the geomagnetic field itself is generated by the dynamo action in the Earth's core. The currents flow according to the Ohm's law, but the electric conductivity is anisotropic because of the effect of the geomagnetic field, and three conductivities are defined. Those are parallel, Pedersen and Hall conductivities, and additionally two dimensional conductivity is used for some purposes. Unit of these conductivities is S/m (=1/(Ωm)), and that of the height integrated conductivity is S.
