abstract = "In this paper we present experimental results obtained by the use
of the method Lightning Mapping Array with Electric Field
measurements on ground (LMA-EF). This method allows to measure the
positions and magnitudes of the electric charges (Q) inside the
thunderstorm clouds. The data used to validate the experiment were
provided by the Vale do Paraiba CHUVA (Cloud processes of tHe main
precipitation systems in Brazil: A contribUtion to cloud resolVing
modeling and to the GPM (GlobAl Precipitation Measurement) )
project campaign, that took place in S{\~a}o Paulo - Brazil
between December of 2011 and January of 2012. The LMA data can
provide us the position (R) of the electric charges centers and a
network of electric field mill provides data of electric field
(E). Combining LMA data with the measurements of electric field on
the ground is possible to determine the magnitude of the electric
charges, by using the inversion of the coulomb law in matrix form:
Q = (RT .R)-1 .RT .E. An algorithm was written to make this
estimation automatically. After the determination of the electric
charge structure, the algorithm recalculates the direct Coulombs
Law and checks the results by fitting data of electric field on
ground.",
