9 years of lightning measurements in South America as detected by STARNET

Abstract

This document presents a brief overview of the Sferics Timing and And Ranging NETwork (STARNET) measurements over South America in the last 9 years. Since its beginning, STARNET measured more than 610 millions of sferics in the entire South America. The main hot spots are found over Maracaibo - Venezuela, northern Argentina, Paraguay, Bolivia, and Corumbá and Amazon basin in Brazil. The detection efficiency and location accuracy is highly dependent on the number of sensors available in the network that it is currently operating 11 VLF antennas.
