Variability of Horizontal Magnetic Field Intensity from Some Stations within the Equatorial Electrojet Belt
Journal Title: Physical Science International Journal - Year 2017, Vol 13, Issue 1
Abstract
The variability of the horizontal component of magnetic field intensity from 7 stations within the Equatorial electrojet (EEJ) belt (±3° of the magnetic equator) has been investigated using year 2008 data measured from the Magnetic Data Acquisition System (MAGDAS) magnetometers. The monthly mean hourly values show variation in the pre-sunrise hours, within the range of 1nT to 21nT. However, dH during the day has a much higher variation than those observed during the pre-sunrise and dusk hours. The presence of Counter electrojet (CEJ) in the morning and evening hours were also observed. Also, equinoctial maximum was observed in most stations, and the horizontal magnetic field intensity over ANC located in the South American sector displays the highest amplitude, while ILR in the African sector appears to have the lowest amplitude.
