dc.description.abstractWe demonstrate a novel method for observing Large Scale Traveling Ionospheric Disturbances (LSTIDs) using high frequency (HF) amateur radio reporting networks, including the Reverse Beacon Network (RBN), Weak Signal Propagation Reporter Network (WSPRNet), and PSKReporter. LSTIDs are quasi-periodic variations in ionospheric densities with horizontal wavelengths >1,000 km and periods between 30 and 180 min. On Nov 3, 2017, LSTID signatures were observed simultaneously over the continental United States in amateur radio, SuperDARN HF radar, and GNSS Total Electron Content with a period of similar to 2.5 hr, propagation azimuth of similar to 163 degrees, horizontal wavelength of similar to 1680 km, and phase speed of similar to 1,200 km hr(-1). SuperMAG SME index enhancements and Poker Flat Incoherent Scatter Radar measurements suggest the LSTIDs were driven by auroral electrojet intensifications and Joule heating. This novel measurement technique has applications in future scientific studies and for assessing the impact of LSTIDs on HF communications.en

We are especially grateful to the amateur radio community who voluntarily produced and provided the HF radio observations used in this presentation, especially the operators of the , , pskreporter.info, and . Blackstone SuperDARN data are made available with support from NSF AGS-1935110. This material is based upon work supported by the Poker Flat Incoherent Scatter Radar which is a major facility funded by the NSF through cooperative agreement AGS-1840962 to SRI International. Algorithms used to calculate the electric field and Joule heating rates were developed under NSF AGS-1853408 and AGS-1552269. GNSS TEC data products and access through the Madrigal distributed data system are provided to the community by the Massachusetts Institute of Technology under support from NSF grant AGS-1952737. Individual contributors of GNSS data are listed in the Open Research section. We gratefully acknowledge the SuperMAG collaborators () who contributed to the SuperMAG database (Gjerloev, 2012) and the SuperMAG SME(r) indices (Newell & Gjerloev, 2011a, 2011b). NAF thanks Rachel Frissell, Bill Liles, Ethan Miller, and Dev Raj Joshi for helpful discussions.en
