Five Single Station Models (SSM's) for hourly monthly median values of the critical frequency of the ionospheric F2 layer (foF2) obtained from vertical-incidence sounding and global IRI-95 and PRIME/CCIR models have been compared using data from 22 European ionospheric stations. The stations are conveniently distributed to cover the COST 251 area (10 degrees W-60 degrees E, 35 degrees N-70 degrees N). The SSM's have been developed within the frame of COST 238 and COST 251 European Projects. The accuracy of the models has been discussed in terms of standard deviation and average percentage deviation. The Kolmogorov-Smirnov test has been also applied. The results show that all Single Station Models (SSM's) give better accuracy than global models and they can provide a remarkable advantage in mapping techniques.

Hourly monthly median values of the critical frequency of the ionospheric layer F2 (foF2) for some European ionospheric stations have been used in order to develop Single Station Models (SSM's). Those models have been compared with long-term mapping PRIME (Prediction and Retrospective lonospheric Modelling over Europe) model. Also a more generally accepted way of using the SSMs in the development of long-term, short-term and instantaneous mapping schemes has been shown. The usefulness of the SSMs as a source of additional screen-point values for instantaneous mapping of the ionospheric parameters has been presented.
