5/16, 7pm, Club Meeting Presentation - F2 Layer Mapping App
In Hamilton Carter's (KD0FNR) words:
Hamie (KO6BTY) and I have been playing with mapping our QSOs for a few years now. We evolved from ionosonde data and Google Earth to data from an NOAA model called GloTEC, (Global Total Electron Content), and Cesium Ion maps. Out of that, we have an app up and running that provides half hour in the past global values for hmF2, (height of the F2 layer at the maximum electron density), foF2, (the frequency a vertical signal will still be reflected back at), and mufd (3000km), (the maximum usable frequency for QSOs on F2 skip at 3,000 km. Hamie and I will talk about what led to the mapping system, how it evolved and was programmed, some of the people we've met and worked with in the NOAA and the Bay Area tech community.
For folks that would like to see the app before the meeting, it can be found at https://copaseticflow.blogspot.com/p/project-toucans-current-f2-map.html
The code is at https://github.com/hcarter333/glotec_hm_fo_f2
This meeting will also be online.
