PERiLS_2023: NSSL Deployable Lightning Mapping Array Data


Data from the NSSL Deployable Lightning Mapping Array during the period of PERiLS_2023 operations. There were five deployments each containing about 48 hours of data. The instrumentation measured VHF emissions to map the three dimensional structure of lightning flashes in space and time. The array consisted of eight NSSL sensors and one TTU sensor. Additionally the IOP4 deployment was near the NALMA and the dataset includes sources identified by those sensors.
