Low Frequency Autonomous Magnetic Field Sensors (LFAMS) Level 1 Data



This data set contains the Level 1 data from the Low Frequency Autonomous Magnetic Field Sensors (LFAMS) sensor network that was deployed in the Mendoza and Cordoba regions of Argentina by the University of Colorado Boulder during the RELAMPAGO (Remote sensing of Electrification, Lightning, And Meso-scale/micro-scale Processes with Adaptive Ground Observations) field season. The Level 1 data are a collection of lightning event data (radio atmospherics or sferics) extrated from the raw Level 0 data from the instruments. The data are in NetCDF format.
