<abstract>
The Ionospheric Group of the National Observatory of Athens operates the Athens Digisonde (URSI code: AT138), one of the most advanced European real-time ionospheric stations, a Digisonde Portable Sounder – 4D (DPS-4D) at Penteli site since September 2000.
</abstract>
<description>
The Athens Digisonde performs 5-minute scheduled observations with vertical incidence ionograms and ionospheric plasma drifts. It provides Ionograms, Skymaps, Drift velocities, Directograms.
