Current Research Interests

Experimental atmospheric electrodynamics and Space and Plasma Physics

Major Projects:
1. CNOFS (Air Force and NASA funded satellite) instrument to study lightning
this satellite, and my instrument recently reentered the atmosphere after a fabulous 8-year life . We are still publishing great stuff from our experiment. Continuing funding has been provided under NSF grant (Lightning Whistlers - Jacobson PI, Holzworth Co-I)

2. WWLLN (World Wide Lightning Location Network) is growing and improving. This past year we have spend enormous time and staff energy working towards combining our raw data with that of the Earth Networks system. We have successfully nearly doubled our detection efficiency in this process. I am very proud of the amazing number of people around the world who are using WWLLN data in their research. Our website lists 20 papers since 2013 - mostly NOT coauthored by my group - which used WWLLN data to make their main points.

3. CARE II rocket experiment. This US Navy sponsored experiment to study dusty plasmas in the ionosphere was successfully launched in September 2015 from Norway. My vector electric field instrument was the prime instrument which worked perfectly, and produced a great data set. We are expecting data analysis funding from the Navy shortly.

4. NOAA GOES-R project for prelaunch validation of the Geostationary Lightning Mapper. WWLLN provides realtime data for this project, and I am working with faculty and students in the UW Atmospheric Sciences department on research about lightning and severe weather.

Volcanic Lightning (WWLLN in the News)
Friday, April 22, 2016
Data from the World Wide Lightning Location Network (WWLLN, managed by ESS) have provided the basis for a new study of explosive volcanic activity in the recent eruption Chile's Calbuco volcano. The study has been highlighted in recent articles of several news sources.
