Abstract

Terrestrial Gamma-ray Flashes (TGFs) are brief bursts of gamma-rays originating in the Earth’s atmosphere and observed on Low Earth Orbit (LEO) satellites. TGFs have a hard spectrum which extends from less than 25 keV to over 20 MeV. The main production mechanism of these bursts of photons is not yet fully resolved. Lightning discharges within 300 km of the sub-satellite point have been found to be closely associated with TGFs. Previous analyses have used World Wide Lightning Location Network (WWLLN) data to geolocate the probable location of TGF source lightning. Recent WWLLN data now also include an indication of lightning power. The distribution of source lightning power will be presented.
