摘要: Sporadic E layers have been observed on a global scale using GPS radio occultation measurements performed by the CHAMP, GRACE and FORMOSAT-3/COSMIC satellites. This has done analysing signal amplitude variations of L1 signal. The distribution sporadic layer occurrence shows strong different time scales with highest rates during afternoon at midlatitudes summer hemisphere. Furthermore, depends several geophysical parameters such as dynamic conditions in lower thermosphere, intensity Earth’s magnetic field meteor flux. connection between dependence these is discussed this chapter.
