AB: LIS is a NASA space borne sensor that identifies the optical emissions of lightning emerging from the top of thunderstorm clouds. LIS data is organized into pulses and then into flashes to produce a product that measures total lightning. EDOT is a ground-based network of "fast antennas" that detect electric field changes. This network is owned and operated by Los Alamos National Lab and currently deployed primarily in Florida. EDOT uses time-of-flight measurements to calculate the source location, time, peak current, event-type classification and, in some cases, emission height. LIS and EDOT lightning parameters complement each other. The calculated instantaneous footprint of LIS defines a subset of EDOT events for Florida and the surrounding seas. Subsets of other available lightning data were also created for the LIS field of view. The subsets are cross-linked to match EDOT events to a specific LIS flash. EDOT events classified as cloud to ground lightning and narrow bipolar events are of particular interest. Both spatial-temporal correlations and anti-correlations will be presented.
