Decrease of the electric field penetration into the ionosphere due to low conductivity at the near ground atmospheric layer
It is well known that lithospheric electromagnetic emissions are generated before earthquakes occurrence. In our study, we consider the physical penetration mechanism of the electric field from the Earth's surface, through the atmosphere-ionosphere layers, and until its detection in space by...

| description | It is well known that lithospheric electromagnetic emissions are generated
before earthquakes occurrence. In our study, we consider the physical
penetration mechanism of the electric field from the Earth's surface, through
the atmosphere-ionosphere layers, and until its detection in space by
satellites. A simplified approach is investigated using the electric
conductivity equation, i.e., ∇ˆσ·∇Φ)=0 in the
case of a vertical inclination of the geomagnetic field lines. Particular
interest is given to the conductivity profile near the ground and the
electric field distribution at the Earth's surface. Our results are discussed
and compared to the models of Pulinets et al. (2003) and Denisenko et al.
(2008). It is shown that the near ground atmospheric layer with low
conductivity decreases the electric field penetration into the ionosphere.
The model calculations have demonstrated that the electric field of
lithospheric origin is too weak to be observed at satellite altitudes. |
