It is well known that geomagnetic field varies in time, as well as in space. Besides, the world magnetic models which are the main sources of information concerning the values of geomagnetic field elements in a particular place, we present more precise and accurate model of these elements covering the territory of Bulgaria. Our study uses information from the last absolute geomagnetic survey involving measurements in 473 points, secular data from Panagyurishte (PAG) and several other Intermagnet observatories near...
