Thunderstorm ground enhancements abruptly terminated by a lightning flash registered both by WWLLN and local network of EFM-100 electric mills.

In this dataset, we present a subsample of 18 TGEs terminated by lightning flashes detected by our recording system that coincide with those found in the database of the World Wide Lightning Location Network (WWLLN). One of the WWLLN’s nodes is located at the Yerevan headquarters of Cosmic Ray Division which operates Aragats research station. The mean value of distance estimated by the WWLLN is 6.6 +/- 5.6 km, by EFM – 4.5 +/- 2.6 (based on 18 TGEs). The times of lightning occurrences measured by Aragats facilities and by the WWLLN coincide within a few microseconds. TGEs were interrupted by lightning during positive and negative near-surface electric fields. The TGEs which started at the negative (positive) near-surface electric field and contracted during the positive (negative) electric field were also observed.
