ABBYNORMAL Model results

The following summary files have been generated from ABBYNORMAL model results using REAL-TIME geophysical indices obtained from the NOAA/SEC space weather service. The ABBYNORMAL model is a physics-based model of the ionosphere from 60 km to 130 km. Above that altitude the resuls are from the International Reference Ionosphere (IRI-2000). The files have the vertically integrated absorption (db's) for an HF signal passing once through the D region. The files are for 2.5, 5.0, 10.0, 15.0, 20.0 MHz signals. These are just representative. Other absorptions values can be calculated by dividing by a factor of the ratio of the frequencies squared. For more information about the ABBYNORMAL model, please contact Dr. Vince Eccles.
