LEE: Combined NSSL and GTRI Lightning Mapping Array Data


Lightning Mapping Array (LMA) sensors were deployed at pre-designated locations for each IOP for the LEE Field Project time period and area of interest. The array consisted of up to 8 GTRI sensors (Units N-X), 8 NSSL sensors (Sites 1-8) and 1 TTU sensor. The network was operated by Georgia Tech Research Institute, National Oceanic and Atmospheric Administration / Office of Atmospheric Research / National Severe Storms Laboratory and OU / CIWRO staff with invaluable assistance from SUNY Oswego faculty and students. This data set includes Level 1 (VHF sources) files. Raw station files (Level 0) uploaded separately. All sensor locations were centered around surrounding the New York Tug Hill Plateau.  See the readme file for more information.
