Data for "Lightning Interferometry Uncertainty, 'Focused Interferometry', and Evidence of Lightning being Ignited by a Cosmic-ray Shower" by Shao et al.

This summarizes the data from our broadband RF interferometric mapping and polarization<br>(BIMAP) system used to produce the figures in the revised manuscript “Lightning Interferometry<br>Uncertainty, “Focused Interferometry”, and Evidence of Lightning being Ignited by a Cosmic-ray Shower”<br>that was originally submitted to the Journal of Geophysical Research (JGR) for publication. Note that the<br>original manuscript was titled ““Focused Interferometry” and Fine Structure of Lightning-Initiating Fast<br>Positive Streamers” and was released with LA-UR-19-32549. In accordance with JGR’s data policy<br>(https://www.agu.org/Publish-withAGU/Publish/Author-Resources/Policies/Data-policy), it is the<br>intention to make this data publicly available at the time of article submission.<br>The data set includes raw BIMAP RF data and processed results for two lightning flashes. The data is<br>available in two files (“FPS_data_20170606_361.sav” and “Small_IC_20180520_205644_408.sav”) which were packaged with using the IDL 'save' command.<br>The raw data includes 3 channels of RF data, 2 channels of RF polarization data, and 1 channel of electric<br>field change data.<br>The processed data includes the RF source positions, source position uncertainties, and the polarization<br>analysis.
