Description

Digital Ionogram Database (DIDBase) collection contains vertical-incidence ionogram measurements and 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. Interpretation of the ionograms allows derivation and computation of actionable numerical information for subsequent use in a variety of applied and research cases.

Access the Data

  • Graphical

    The DIDBase WebPortal is a landing page for browsing and display of ionogram images. IMPORTANT: Each image shows the best available scaling, which can be manually scaled record if available. The scaler information is shown at the bottom of the left column of scaled data values. To analyze only autoscaled evaluated data, use SAO Explorer (see instructions in the SAO Explorer tab).

    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: SAO Explorer retrieves the whole set of scaling record per each ionogram. Should numerical or display product be produced by SAO-Explorer, the best available scaling is selected, which is manually scaled if available. To retrieve only autoscaling scaling data for analaysis, in the View menu, select Options submenu, and in the "Export" tab, check off the "Use currently selected scaler (human or ARTIST) for all export operations". Then select the relevant ARTIST scaling in the main SAO Explorer window, using the scaler drop-down menu left of the Measurement Time drop-down menu.

    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, which is manually scaled if available. To use only autoscaled data for analysis, use SAO Explorer (see instructions in the SAO Explorer tab).
