Ultra-Slow Discharges that Precede Lightning Initiation dataset

Description of Dataset:

These data were used to produce figures for the Geophysical Research Letters publication: Ultra-Slow Discharges that Precede Lightning Initiation. Data are provided in human readable ".csv" and ".dat" formats.

Arrays within the in csv files are stored in rows, headings for each row are the array titles. The arrays t, x, y, z are the time, easting, northing, and altitude for arrays after cuts have been performed, while the cutT, cutX, cutY, and cutZ are the corresponding arrays for the t, x, y, z data that have been cut from the fit. The fitT, fitX, fitY, and fitZ are the fit curves for t, x, y, and z. The hist_bins, binwidth, hist, xPDF, and PDF are the bins, bin width, histogram counts, PDF x values, and PDF for the lateral spread from the fit. All data values are in milliseconds and meters.

The arrays within the dat files are stored in equally spaced rows. The first row contains the header and array names for the columns. Data for TRI-D plots contains the source index, time in milliseconds, easting in kilometers, northing in kilometers, altitude in kilometers, and intensity in units of galactic background. For the impulsive image figure (FigureS5_data.dat, Supplemental figure S5), the data are the block index, time in milliseconds, easting in kilometers, northing in kilometers, altitude in kilometers, and the \(\chi^2\) for the located source.
