A case study is presented which demonstrates the value and validity of a novel approach to use consolidated amateur (‘ham’) radio reception reports as indicators presence intense ionospheric sporadic E (Es). It shown that data can provide an important supplement other techniques, allowing detection tracking Es where no suitable ionosonde or measurements are available. The effectiveness demonstrated by reference data, advantages limitations technique discussed.
In the E-region of ionosphere, at heights between 90 and 130 km, thin patches enhanced ionization occur intermittently. The electron density in these sporadic-E (Es) clouds can sometimes be so high that radio waves with frequencies up to 150 MHz are obliquely reflected. While this phenomenon is well known, reflection mechanism itself not understood. To investigate question, an experimental system has been developed for accurate polarimetric fading measurements 50 reflected by mid-latitude Es...
The amateur radio community is a global, highly engaged, and technical with an intense interest in space weather, its underlying physics, how it impacts communications. large-scale observational capabilities of distributed instrumentation fielded by operators science enthusiasts offers tremendous opportunity to advance the fields heliophysics, science, weather. Well-established networks like RBN, WSPRNet, PSKReporter already provide rich, ever-growing, long-term data bottomside ionospheric...

Mid-latitude sporadic-E (Es) is an intermittent phenomenon of the lower E region ionosphere. Es clouds are thin, transient, and patchy layers intense ionization, with ionization densities which can be much higher than in background Oblique reflection radio signals very high frequency (VHF) range regularly supported, but mechanism for it has never been clearly established—specular reflection, scattering, magnetoionic double refraction have all suggested. This article proposes using...
