Real-Time Observations


The National Observatory of Athens operates one of the most advanced European real-time ionospheric stations, a Digisonde Portable Sounder - 4D (DPS-4D) at Penteli site (38oN, 23.5oE). For more details on the instrumentation, see Athens Digisonde. 
The visitors of this website can access real time observations updated every 2 min as well as archived observations from the recent period.
SAO Long-term Archive tool gives access to all archived observations of the Athens Digisonde in SAO format. Users can also display time plot series of all available ionospheric characteristics.
