             abstract = "Low-level currents measured prior to return strokes can 
                         potentially provide information about the properties of upward 
                         leaders during lightning flashes. However, these currents need to 
                         be properly analysed and interpreted in order to be useful for 
                         evaluating upward connecting leaders. In this paper, low-level 
                         currents measured before return strokes in two lightning events to 
                         two structures in Brazil are analysed and interpreted as case 
                         studies. The discharge current estimated from one of these events 
                         is used as input to a detailed thermo-hydrodynamic model with an 
                         extensive kinetic scheme for N2/O2 mixtures. The model allows the 
                         evaluation of the physical and chemical properties of upward 
                         connecting leaders. Estimates of the temperature, mass density, 
                         electric field and radius of the channel are presented for an 
                         upward connecting leader propagating in a lightning event. In 
                         addition, estimates of the axial density of electrons, ions and 
                         neutral particles (including NO and NO2) are also reported.",
