ANALYSIS OF GEOMAGNETIC FIELD DATA FROM MEASUREMENTS DURING 2003 IN MACEDONIA

Abstract

Maps were compiled on the basis of the geomagnetic field measurements (I, D, F) carried out in 2003 in the territory of the Republic of Macedonia. Values of I, D, and F were calculated using the IGRF model. In 2003 geomagnetic measurements were performed at 15 repeat stations. Isolines of the geomagnetic elements were drawn with the SURFER program package. The normal dependences of the geomagnetic field on geographic latitude and longitude and the altitude of repeat stations were not taken into consideration during the processing. Approximations drawn in this manner make it possible to analyze the results relative IGRF model results. Such an approach is possible if one bears in mind that the territory of Macedonia is within Δφ = 1°31’ and Δλ = 2°35’ interval, its surface area is P = 25713 km², and the highest repeat station is 1684 meters above sea level.
