Resumen:
During October and November 2003 two geomagnetic storms occurred having different behaviors. The large number of IGS GPS permanent stations at high Northern latitudes allows monitoring the behavior of the vTEC over the region.This paper presents a method based on GPS observations from more than 40 stations distributed around the North Pole to produce half-hourly sequences of vTEC polar maps from 50º to 90º N latitude. The method does not use any analytical function like spherical harmonic to map the vTEC. The results are shown for four days of October (from 27th to 31st) and for three days of November (from 19th to 21st) taking into account the development of the storms as seen by different geomagnetic indices. The presence of high latitude localized structures in vTEC during the geomagnetic events are described and analyzed.
