0007 ABSTRACT
ABSTRACT
This work has two specific divisions: The first studies the relationship between the amount
of lightning region in which the AMAS is closer to the surface compared to other regions
outside the ”dip” of inner Van Allen belt. The second is the variation of probing radio propagation
radio frequency in the range of 7.00 MHz, influenced by the conditions ion of the
upper atmosphere, which in turn are influenced by solar activity.
Key words: radio, monitoring, measurements, noise, ionosphere, solar cycle.
