An automatic quality factor for Autoscala foF2 values Original Research Article

We propose a new parameter for quality evaluation of ionogram traces reconstructed by Autoscala. This parameter efficiently assesses the reliability of the automatic interpretation of ionospheric characteristics. Based on an extensive analysis of the data, the parameter values are statistically associated with the accuracy of foF2 data automatically scaled by Autoscala. Therefore, Autoscala will be improved by providing foF2 accuracy as supplementary output information.
