Photometric Measurements of Lightning Phenomena with Simultaneous Radio Frequency Data

This data was collected with a novel multi-band optical instrument alongside simultaneous radio frequency measurements for 16 lightning flashes.

The transmissivity of 3 narrowband optical filters used to collect photometric data for temperature analysis are stored in the filterData folder along with the responsivity of the photodiode used to collect the data. 

The flash data is stored by flash in folders labeled with the UTC day and time in a MonthDDYYY_HHMMSS format. For each flash, there is an overview flashFigure.pdf that quickly summarizes the flash by plotting the Lightning Mapping Array (LMA) data and some of the data stored in PicoScope.csv including the Fast Antenna data, the Slow Antenna data and the 777 nm data measured at the ground. Some of the flashes were also seen by the Geostationary Lightning Mapper (GLM), this data is included on the flashFigure.pdf file when available as well as fully reproduced in the GLM.csv file. For each flash, the LMA data is stored in the LMA.dat file, the photodiode and electric field antenna data are stored in the PicoScope.csv file as well as the time in milliseconds after the trigger occurs in UTC time (the millisecond precise data is stored in the name of the time column in the PicoScope.csv). Each PicoScope file has some pre-trigger data, this is denoted with a negative time value in the time column as it is before the trigger event. Finally, the temperature is reported in the Temperature.csv file, it was based off of a decimated version of the PicoScope file to reduce the computational time but it's time units are still milliseconds after the trigger occurs in UTC time like the data in PicoScope.csv.
