ABSTRACT
On 24 August 2007, 22:53 UT, a balloon was launched from Langmuir Laboratory, New
Mexico, and was carried about 25 km east by the wind, traveling at an altitude that varied
between 2500 m up to 13300 m above sea level. An electric field sonde (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 48 minute balloon flight, 70 cloud-to-ground (CG) flashes occurred within 15 km of the
balloon. Using the Esonde data and the LMA data, along with recently developed analysis
techniques, the charge transport associated with flashes near the balloon was estimated.
Results for several interesting flashes will be presented, including a 13 stroke CG flash
and an IC flash whose channel is within 200 meters of the Esonde. The close proximity
