<description>The Equatorial Plasma Bubbles (EPB) detection tool is a method to identify the occurrence and its main observables (duration, depth of the depletion and the total disturbance)
with data gathered from receivers of Global Navigation Satellite System (GNSS). This method adapts a previously existing technique to detecte Medium Scale Travelling Ionospheric
Disturbance (MSTIDs), which focuses on the second derivative of the total electron content (TEC) estimated from GNSS signals.</description>
