Magnetic declination of the territory of Ukraine: the results of observations and calculations
Journal Title: Геофизический журнал - Year 2015, Vol 37, Issue 2
Abstract
A technology is proposed for calculating the strength and angular components of the vector of the induction of the Earth's magnetic field. The technology is based on the development of a three-dimensional model of the earth's crust and the calculation of the northern (∆Вах), eastern (∆Ваy) and vertical (∆Ваz) components of the anomalous magnetic field from it, which, together with the corresponding components (В0х, В0y, В0z) allow us to determine the total values of the Вх-, Вy-, Вz-components of the Earth's magnetic field. With their use, the horizontal component (BH) of the geomagnetic field vector and the angles of its declination D and the inclination J are calculated. The values of the magnetic declination D in the territory of Ukraine for the epoch of 2010 are calculated (varies from –6 ° to +20 °) and the secular run for the period 2010—2015 (6.0—7.5 min/year). The contribution to the value of the magnetic declination D of its normal (D0) and anomalous (ΔD) components is estimated. The accuracy of the calculated values of D is estimated by comparison with the measured values of magnetic declination at magnetic observatories and points of secular run. For most points, the difference is about 3—6 minutes. Currently, the results of calculating the magnetic declination D for the time interval of 2010—2015 are used by the state services of Ukraine ("UkSATSE", "Topographic Service of the APU") to ensure flight safety and compiling topographic maps.
