Because of the poor coverage of this area with geomagnetic data, especially at the borders of this cap, we calculated from IGRF-11 field model the corresponding synthetic Cartesian X, Y, Z components at sea level in 19 fixed points of this area, at years 1990 , 1995 2000 and 2005 (circles in Fig. 1(a)).
