AB: On 18 August 2004, 19:46 UT, a balloon was launched from Langmuir Laboratory, New Mexico, and was carried about 30 km southeast by the wind, traveling at an altitude that varied between 2500 m up to 4300 m above sea level. An electric field sonde or Esonde measured the electric field during the flight, while simultaneously, New Mexico Tech's Lightning Mapping Array recorded the location of VHF pulses generated during lightning. During the 40 minute balloon flight, 182 flashes occurred within 15 km of the balloon; 41 of these flashes were cloud-to-ground flashes. Using the Esonde data and the LMA data, along with recently developed analysis techniques, we estimate the charge transport associated with the lightning occurring near the balloon. This analysis leads to a picture for how charge flows in the 30 km region observed by the balloon-borne E-field change instrument.
