Research Locations: Arrival Heights / Cusp Lab / Terra Lab
Extremely Low Frequency/Very Low Frequency (ELF/VLF) observations at McMurdo, South Pole, and Palmer Stations provide a deeper understanding of lightning and its effects on the Earth's inner radiation belt. Lightning source currents are estimated or directly measured by experimental observations of individual natural and rocket-triggered lightning flashes in North America. Together, the North American and Antarctic datasets are used to experimentally identify and analyze the components of lightning and the effects of lightning that are observed in the Antarctic, more than 10,000 kilometers distant. This project directly supports the continued operation of the ELF/VLF radiometers at all three US Antarctic research stations. At Arrival Heights, the radiometer has operated continuously for nearly 25 years, providing a unique resource for long-baseline ELF/VLF noise measurements, Schumann resonance observations, and global climate-change parameterization via global lightning detection. The recently upgraded data acquisition system continuously records ELF and VLF data streams and provides real-time data processing and access via the Internet.
Field Season Overview:
This season, researchers will continue to continuously record ELF/VLF data and provide real-time data processing and access via the Internet, when available, in support of coordinated lightning-related experiments to be performed in North-Central Florida. Minor support will be provided on station throughout the year by contract research associates. Field team members will conduct extensive noise surveys at both McMurdo and South Pole stations. The existing VLF antennas at Palmer Station will be removed from the glacier and relocated to the “backyard” at Palmer Station or to Bonaparte Point with support from the riggers on station in April 2014.
