Abstract:
This work succinctly narrative the longitudinal variability of the horizontal component
of earth's magnetic field along equatorial region by using ground base magnetometer
data observed at equatorial stations of Guam, Apia, Mbour and Addis Ababa.
Grasped 20014 the earth's magnetic field data from each stations and has been written
MATLAB script by imported into MATLAB program to obtain a clear graphical
, of horizontal component of the earth's magnetic field on the daily, monthly and
seasonally difference. of each stations.
The outcome displayed that, on the daily variation of ground base magnetometere
~
stations· the sun is overhead almost the same local time (around 12:00 LT) with
exceptional Senegal at about 10:00 LT and cowling conductivity is inconsistently
ascending and descending. On the monthly variation the horizontal earth's magnetic
~ '· field is consistently increase in the daytime and decrease during nighttime. Within the
same day, month and year the H component of the earth's magnetic field intensities
were/varies from one station to the others. consequently, an excessive ionospheric
current was observed at Addis Ababa and the cowling conductivity was also high on
the Ethiopia sector .
