About Amira Shimeis

My rotine work Montoing the solar activity and its effect on magnetosphere and ionosphere.I have been finished diploma of machine learning. ‎‏I studied the physics of the ionosphere with muti-instruments(GPS CIDR) in my Msc.and Ph.D. As part time,I am a lecturer at physics department faculty of science Helwan University for many courses.Ph.D.title:“Solar impact on the ionized layers at the crest of the equatorial anomaly in the African longitude sector of the Northern Hemisphere”At the equator the fountain effect (motion of plasma upward at the equator and downward at tropical latitudes) creates in the F equatorial region (F region: altitude range below 200km and 600km) a through of ionization at the latitude of the magnetic equator and two peaks of ionization in the northern and the southern hemispheres at 10° latitude of the equator. Egypt is located below the northern peak of ionization. The Houston University radar CIDR and the SCINDA Boston University GPS, allow for the first time measurements of total electron content (TEC) in Egypt. TEC is mainly related to the F region ionization.So, we use new data to characterize for the first time the crest of ionization in the African longitude sector (Northern hemisphere).Shimeis, A, I.
