Comparison of the main ionospheric parameter values measured by Digisonde at Irkutsk in 2003 with the IRI model data
Abstract
This paper summarizes a one-year-long run of ionospheric condition observations made by the digisonde (DPS-4) at Irkutsk (52.5N, 104.3E). Presented are the results derived from comparing the values of the main ionospheric parameters (the critical frequency, and the height of the F2-, F1- and E-layer maxima) obtained by the DPS-4 in 2003 with the IRI model data. In order to exclude the error associated with the prediction of the solar activity index F10.7, the model values were calculated on the basis of the values of the index F10.7 measured with the Ottawa and Penticton radio telescopes. An analysis was made of the following aspects related to the comparison of the measured and model parameters. 1. Differences in median values. 2. Daily deviations of parameters from model values. 3. Relationship of daily deviations with daily variations of F10.7. 4. Geomagnetic activity influence on disagreements between the model and measurements
