The 135 files in this directory contain all data required to reproduce the results of LaBelle [2021] "Flickering Low Frequency Auroral Hiss". The filenames have format: extract-YYYYMMDD-HHMM-HHMM-SP-USRP-CH0.dat-in.gz, where YYYY is the year (2019 for all of the data in this set), MM is the month, and DD is the day; the first HHMM gives the time of the first spectrum in the file in hours minutes; the second HHMM gives the time of the last spectrum in the file in hours minutes; and SP stands for the site where the data were recorded (SP for South Pole for all of the data in this set). Each file covers a time interval of 1-60 minutes between June 11 and October 3, 2019. When unzipped, each file has this format: sets of 129 lines, each corresponding to a power spectrum; the first line in each set of 129 lines is time of that spectrum in format HHMM:seconds (on the date encoded in the filename), and lines 2-129 in each set of 129 lines are the relative powers in tenths of decibels corresponding to evenly spaced frequency bins ranging from 0-1000 kHz. These power spectra were obtained by combining signals from two crossed antennas at South Pole Station, Antarctica. The original data consisted of 2M IQ samples per second on each antenna, corresponding to a bandwidth of 2 MHz and a center frequency of 1 MHz. They were analyzed by taking averages of four consecutive 256-point FFTs with Hanning window applied. Only the first half of the resulting transform (128 bins, corresponding to 0-1 MHz) were saved. These are the data in the above files. These data were used for all subsequent analysis presented in LaBelle [2021] paper entitled "Flickering Low Frequency Auroral Hiss"
