ionosphere
This data set consists of broadband VLF data that is used to calculate polarization for the paper titled "Polarization-Based VLF Remote Sensing of Transient Ionospheric Disturbances." The data is collected on two orthogonal magnetic loop antennas with 16-bit resolution at 100 kHz sample rate, with timing provided by a GPS-trained oscillator. EG is East Granby, Connecticut, and CN is Chapel Hill, North Carolina. The start dates and start times for the file are encoded in the file title: YYMMDDHHMMSS.

This dataset was obtained from the ionogram at Kupang in 2022 to investigate the frequency window of the Near Vertical Incidence Skywave (NVIS) channel with homogenous Time of Flight (ToF) values. All data is in the form of.mat files (MATLAB). The first dataset is in Matlab variables ('DataWidthFrekHourly','DataCenterWidthFrekHourly'), which consist of maximum window frequency values with homogenous ToF and the center frequency of the widest window. The structure of the data array is 96x365, with the row as the time (1:96) and the column as the day in one year (1:365).

Radio Frequency (RF) signals transmitted by Global Navigation Satellite Systems (GNSS) are exploited as signals of opportunity in many scientific activities, ranging from sensing waterways and humidity of the terrain to the monitoring of the ionosphere. The latter can be pursued by processing the GNSS signals through dedicated ground-based monitoring equipment, such as the GNSS Ionospheric Scintillation and Total Electron Content Monitoring (GISTM) receivers.
