Amateur Radio Spot Data for "First Observations Linking Large-Scale Traveling Ionospheric Disturbances to Polar Vortex Strength"

This repository contains the raw data amateur radio data used to compute the Large Scale Traveling Ionosphic Disturbance activity presented the
Geophysical Research Letters manuscript
"First Observations Linking Large-Scale Traveling Ionospheric Disturbances to Polar Vortex Strength".

This dataset has monthy *.tar files containing daily bzip2 Comma Separated Value (CSV) files of data from the following amateur radio spotting networks for the time period November 2018 - May 2019:

1. PSKReporter (https://pskreporter.info/)
2. Weak Signal Propagation Reporter Network (WSPRNet, https://www.wsprnet.org/)
3. Reverse Beacon Network (https://reversebeacon.net/)

Where necessary, spots have been geolocated using latitudes and longitudes from https://www.qrz.com/.

We are grateful to the operators of PSKReporter, WSPRNet, and the Reverse Beacon Network for the use of their data.

The columns of each CSV file correspond to the following values:

# [0] UTC Datetime 
# [1] Transmitter Call Sign

# [6] Receiver Maidenhead Grid Square
# [7] Receiver Geographic Latitude
# [8] Receiver Geographic Longitude
# [9] Source of Receiver Gride Information
#
# [11] Frequency (Hz)
# [12] Signal to Noise Ration (SNR) [dB]
# [13] Mode
#
# [14] Source
# [15] Sender Status
# [16] Inter-Modulation Distortion (IMD)
# [17] ipOriginID
# [18] sendeMobileLocator
# [19] c1
