NO.2004SUMMER - now: Field projects of launching balloon-borne instrumetn (Esonde) to measure electric field inside New Mexico thunderstorms. NO.2004SUMMER: Participate in the coordinated field project of laser-triggered lightning (not successful) NO.2006SUMMER: Captured a daytime video of an upward positive junction leader (the analysis is being converted into a publication). NO.2007SUMMER: Video imaing system of red sprites over New Mexico thunderstorms (along with an audio recording system) (in progression). NO.2007MAIN: Integration of Hybrid of E-100 field mill and slow antenna (accomplished in the summer of 2007). This apparatus is able to collect electric field and electric field change data simultaneously.

NO.2005FALL: Develop a least-squares optimization model to study the detailed charge transfer in intracloud flashes. (to be present in the dissertation for Ph.D. degree) NO.2007FALL: Calibration of the new instrument (Eturtle). (accomplished) NO.2007FALL: Develop a least-squares optimization method to estimate two componetns of the horizontal thunderstorm electric field from Esonde data. (accomplished with the help of Dr. Hager, from Mathematics Department, University of Florida)
