Progress on Artist Improvements

Abstract

Digisonde ionograms are automatically scaled in ARTIST (Automatic Real Time Ionogram Scaler with True Height). The presence of multiple Es traces had caused errors in the autoscaling. New software has been developed that allows to properly track the F trace by identifying the multiple Es echoes before the F trace identification is initiated. Multiple F traces are also identified in order to more securely identify the IF trace in the presence of mixed-mode echoes (M and N traces). The new ARTIST software is now operative and very robust for difficult ionograms. Keywords: Ionograms; Autoscaling; Expert systems.
