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

<p>This repository contains the raw data amateur radio data used to compute the Large Scale Traveling Ionosphic Disturbance activity presented the<br>Geophysical Research Letters manuscript<br>"First Observations Linking Large-Scale Traveling Ionospheric Disturbances to Polar Vortex Strength".</p> <p>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:</p> <ol> <li><a href="https://pskreporter.info/" target="_blank" rel="noopener">PSKReporter (https://pskreporter.info/)</a></li> <li><a href="https://www.wsprnet.org/" target="_blank" rel="noopener">Weak Signal Propagation Reporter Network (WSPRNet, https://www.wsprnet.org/)</a></li> <li><a href="https://reversebeacon.net/" target="_blank" rel="noopener">Reverse Beacon Network (https://reversebeacon.net/)</a></li> </ol> <p>Where necessary, spots have been geolocated using latitudes and longitudes from <a href="https://www.qrz.com/">https://www.qrz.com/</a>.</p> <p>We are grateful to the operators of PSKReporter, WSPRNet, and the Reverse Beacon Network for the use of their data.</p> <p>The columns of each CSV file correspond to the following values:</p> <p># [0] UTC Datetime&nbsp;<br># [1] Transmitter Call Sign<br># [2] Transmitter Maidenhead Grid Square<br># [3] Transmitter Geographic Latitude<br># [4] Transmitter Geographic Longitude<br># [5] Source of Transmitter Gride Information<br>#<br># [6] Receiver Maidenhead Grid Square<br># [7] Receiver Geographic Latitude<br># [8] Receiver Geographic Longitude<br># [9] Source of Receiver Gride Information<br>#<br># [11] Frequency (Hz)<br># [12] Signal to Noise Ration (SNR) [dB]<br># [13] Mode<br>#<br># [14] Source<br># [15] Sender Status<br># [16] Inter-Modulation Distortion (IMD)<br># [17] ipOriginID<br># [18] sendeMobileLocator<br># [19] c1<br># [10] c2<br># [21] mode2</p> <p># Computed Fields<br># [22] Great Circle Short Path [km]<br># [23] Great Circle Short Path Midpoint Geographic Latitude<br># [24] Great Circle Short Path Midpoint Geographic Longitude</p> <p>This dataset is designed to be used with the LSTID autodetection software available at <a href="https://doi.org/10.5281/zenodo.13630867" target="_blank" rel="noopener">https://doi.org/10.5281/zenodo.13630867</a>.</p>
