Models of the normal geomagnetic field in the Republic of Macedonia

The paper presents the explorations of the normal geomagnetic field for the period 1990- 2010. The models are made for the elements of the normal geomagnetic field for the epochs 1990, 2005 and 2010. Investigated area has complex geological and morphological structure, so in the definition of the normal geomagnetic field were included influences of the regional geomagnetic structures and the relief in Macedonia. Because there is no geomagnetic observatory in Macedonia, in explorations are used data from the neighboring observatories, especially Panagyurishte in the Republic of Bulgaria and Grocka in the Republic of Serbia. Мodel of the elements of the normal geomagnetic field for the epoch 2010 is valid in the next five years
