  Research Groups: Space Physics

Areas of Interest:
Experimental atmospheric electrodynamics and Space and Plasma Physics

Education:
Ph.D., Physics, University of California, Berkeley, 1977

Current Research Interests:
Research: Presently funded research includes balloon, rocket and satellite instrumentation relating to experiments in space physics and atmospheric electrodynamics.

(1) Sprite Balloon experiment: NSF funded (ATM -0091825) experiment to make direct in-situ measurements of the electromagnetic environment of red sprites in the stratosphere.
(2) Equatorial ionospheric plasma irregularity investigation on the CNOFS satellite. Instrument is an optical lightning detector which is part of the VEFI vector electric field instrument (with R. Pfaff/NASA) (supported by NASA under grant NAG5-11675) to be launched in 2003.
(3) Antarctic balloon experiments to study megnetospheric dynamics. This NSF sponsored experiment involves instruments on balloons to be launched with the Japanese (NIPR)and later in coordination with UCBerkeley (D. Smith). Our instruments make vector electric field measurements. Launches scheduled for this year and next. (OPP-126028)
(4) DROPPS: Distribution and Role of Particles in the Polar Summer mesosphere Using Coordinated Rocket, Radar and Lidar Techniques (with R.A. Goldberg/NASA/GSFC) - wherein I provided the vector electric field booms and sensors for two rockets launched in 1999 into a strong PMSE (Polar Mesospheric Stratospheric Echo) region and the other into a strong NLC (Nocilucent Cloud) - NASA NAG5-5183
(5) Thunderbolt: in which I provided an optical lightning sensor for a rocket launched over a thunderstorm in 2000 (with J. Wygant/Univ. of Minn. and M. McCarthy/UW) - NASA NAG5-5190
(6) ELBBO: Extended Life Balloon Borne Observatories: in which I provided 6 balloon payloads which measured stratospheric electric fields and included the record duration stratospheric flight of over 4 months. NSF ATM9987684.
