N2 - This paper reviews the data-based approach to modeling the distant magnetospheric magnetic field. Large amount of the spacecraft magnetometerdata, accumulated since the beginning of the space era, allowed to developa quantitative representation of the magnetospheric configurations, based onmeasurements made within a vast region extending to the Moon's orbit. Thetask of modeling the distant geomagnetic field is largely complicated both byits dependence on seasonal/diirnal changes of the Earth's dipole tilt angle and asignificant variability caused by the solar wind fluctuations and magnetosphericsubstorms. Though widely used in various experimental and theoretical studies'the existing models provide only average and often too crude approximationsfor highly variable actual field. This review discusses the fundamentals of thenest-generation models, including the problem of their calibration by the solarwind parameters, modeling the field from Birkeland currents, and a new approachto fitting models against data.
