IBP Model Updates
January 2025
The IBP (Ionospheric Bubble Probability) model version 1.3 is now available to the community through the CCMC instant-Run (IR) service.
The IBP model is an empirical model to predict the occurrence probability of post‐sunset equatorial plasma depletions (EPDs) derived from 9 years of CHAMP and 9 years of Swarm magnetic field measurements. The model predicts the occurrence probability of EPDs for a given longitude, day of the year, local time and solar activity, for the altitude range of about 350–510 km, and low geographic latitudes of ±45°.
