Continuous monitoring and investigation of the ionosphere is important part of Space
Weather research as the ionosphere affects heavily the communication, remote sensing, and
navigation systems. Among the most important factors that force the ionosphere are solar and
geomagnetic activity. The ionosphere can be described by means of electron densityprofile and
derived parameters (total electron content, critical frequencies, height of layers). Ground
measurement of the ionosphere is provided routinely by the network of ionosondes/Digisondes.
The GPS based techniques and empirical models (namely IRI-Plas) were used by the IONOLAB
group to recover electron density profiles using the computerized Ionospheric Tomography
(CIT). The data were obtained from databases www.izmiran.ru/ionosphere/weather/, IONOLAB
web page www.ionolab.org, GIM ftp://cddis.gsfc.nasa.gov/gps/products/ionex/, DIDB and
spidr.ngdc.noaa.gov/spidr/. We compare the ionospheric characteristics from periods of
enhanced geomagnetic activity at the sites of European midlatitude Digisonde measurement, and
GPS based technique using the IONOLAB-TEC model. These results are compared with the
results from quiet preference periods of low geomagnetic activity. The work was supported by a
Joint project T?BITAK 114E092 and AS CR 14/001, and Grant GA15-24688S.
