The ionospheric studies have been carried since 1995 by Institute of Geodesy Warmia and Mazury University in Olsztyn jointly with West Department of the IZMIRAN of the Rnssian Academy of the Sciences in Kaliningrad. GPS measurements from 100 European EPN/IGS permanent stations were used to monitor the ionospheric effects of geomagnetic storms. A series of ionosphere maps were produced to present the spatial distribution of TEC. The dense network of GPS stations in Europe allows to obtain high spatial and temporal resolution of TEC. Our estimation technique provided TEC maps with 15min interval and with a spatial resolution of 150-350 km. As the examples we analysed geomagnetic disturbances, which occurred during the months of September 1999 and March 2001. It was found that the storm essentially modified the ionosphere. During the storm the large and medium-seale irregularities were detected in the high-Iatitude ionosphere as well as at middle latitudes. The deep spatial TEC changes were caused by oceurrence of the main ionospheric trough, which during the storm moved in the direction of the Equator (to latitude of about 50 st. N).
