Abstract text:

The HamSCI Grape Personal Space Weather Station citizen science project is designed to study ionospheric variability using a network of low-cost, high frequency (HF, 3-30 MHz) Doppler receivers. These receivers monitor highly stable signals broadcast by US and Canadian governmental standards stations WWV (Ft. Collins, Colorado), WWVH (Kauai, Hawaii), and CHU (Ottawa, Ontario). Due to the use of these high-stable and carefully calibrated transmitters, paired with precision frequency measurement by the Global Navigation Satellite System (GNSS)-disciplined Grape receivers, variability of the received frequency can be attributed to ionospheric variability. To study the ionospheric and radio propagation impacts of the upcoming October 14, 2023 annular and April 8, 2024 total solar eclipses, a network of Grape receivers is being deployed to volunteer amateur radio operators and citizen scientists across the US. This data from these receivers will be sent to a central Personal Space Weather Station database and made available for public access via a web interface. In this presentation, we describe the current operation of this system, as well as planned improvements to public data access and visualization.
