| Summary: | Earth magnetic data can be measured by magnetometer, Magnetic Data Acquisition System and other devices. MAGDAS is a realtime system magnetometers that are being deployed by Kyushu Sangyo University of Fukuoka, Japan. On the April 2007 the deployment was concentrated along the 210 magnetic meridian. However, during the current stage of expansion, units are also being deployed along the geomagnetic equator, in places such as Malaysia, Ethiopia, Nigeria, Ivory Coast, and also Brazil. The ordinary data from the MAGDAS can be used for studies of long-term variations, like magnetic storm and auroral substorms, while the induction-type will be useful for studies of ULF waves, transient and impulsive phenomena. The earth magnetic data from the MAGDAS can also be used as part of earth magnetic data monitoring, mainly for earth events such as earthquake and space events such as geomagnetic storm. For this project, data from stations at the north, equatorial and south region are considered as monitored data to be analyzed. The data will be taken at stations located at Onagawa, Japan, Langkawi, Malaysia and Cooktown, Australia. The data is taken at different latitude and longitude to see the different of earth magnetic field and its characterization. The analyses are based on the different biases of MAGDAS data at different region. From the analysis, the earth magnetic polar at different region can be mapped and defined. The results are useful to give the regional of magnetic format data. |
