Description
Digital Ionogram Database (DIDBase) collection contains vertical-incidence ionogram-derived information acquired by Global Ionosphere Radio Observatory (GIRO), https://giro.uml.edu, a network of ionosondes (high-frequency remote sensing sounders). Ionosondes detect echoes of the probing signal of varying frequency that correspond to reflections of the vertically transmitted signal from various locations in the ionosphere illuminated by the signal. Resulting image of the signal strength as function of the operating frequency and the time of flight is called ionogram. When viewed in the ionogram frame, signal echoes form traces that correspond to different plasma layers in the ionosphere. The raw ionogram data are also available from DIDBase for most observatory sites (a different Data Collection). Interpretation of the ionograms allows derivation and computation of actionable numerical information (Level 2) for subsequent use in a variety of applied and research cases. This collection holds manually scaled (validated) data, Level 2V. Enable "manually only" option of the data search in order to get only manually scaled ionograms.
Access the Data
3 Links
-
The DIDBase WebPortal is a landing page for browsing and display of ionogram images. IMPORTANT: Each image shows the best available scaling, which may be an autoscaling. The scaler information is shown at the bottom of the left column of scaled data values. To retrieve only verified-clean scaling data, use SAO Explorer with DIDBase query.

The SAO Explorer installation and documentation page. SAO Explorer is the main visualization and editing tool for ionogram and ionogram-derived data in DIDBase. IMPORTANT: To retrieve only verified-clean scaling data, select checkbox "Only manually scaled data" in the DIDBase query window.

FastChar is a landing page for the LGDC servlet to retrieve numerical ionogram-derived data in DIDBase, formatted as a plain-text tabulation IMPORTANT: FastChar shows the best available scaling data for the given time and location, which may be autoscaled. To use only verified-clean scaling data, look for rows with CS (confidence score) of 999. To retrieve only verified-clean scaling data, use SAO Explorer with DIDBase query for only manually-scaled data.
