Polar Cap Patches Detected with RISR-N

<h3>Database of Polar Cap Patches detected with the North face of the Resolute Bay Incoherent Scatter Radar (RISR-N)</h3> <p>This dataset was generated by applying two polar cap patch detection algorithm described to the full RISR-N database.</p> <p>The Ren2018 algorithm was first described in&nbsp;<a href="http://https//doi.org/10.1029/2018JA025621">Ren et al., 2018 (doi:10.1029/2018JA025621)</a>.&nbsp; It includes the time, peak, and prominence of all detected patches, asd well as the average electron and ion temperature and electron density within each patch.</p> <p>The Perry2018 algorithm was first described in <a href="https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2018RS006600">Perry &amp; St. Maurice, 2018 (doi:10.1029/2018RS006600)</a>.&nbsp; Instead of a list of patches, this algorithm generates a patch index for each time in the database which corresponds to the percentage of the F-region FoV filled with patches.</p> <p>The script that generates this database in available on GitHub: <a href="https://github.com/Polar-Cap-Scintillation/polar_cap_patch_detection">Polar-Cap-Scintillation/polar_cap_patch_detection</a></p> <p>Version 4 of this dataset includes RISR-N data through 2024 and has an error corrected that may cause some patches to be counted multiple times in the earlier versions.</p>
