Evaluation of the effect of sporadic-E on high frequency radio wave propagation in the Arctic

High Frequency (HF) radio propagation, and applications such as Over-The-Horizon Radar (OTHR), is sensitive to ionospheric disturbances caused by space weather. Improved modelling monitoring techniques for the high-latitude polar regions supports high quality OTHR long-range surveillance. One disturbance Sporadic-E, a phenomenon in which thin enhancement E-region (approximately 90–150 km altitude) electron density acts strong reflector of HF waves. In this study, we perform case study effect sporadic-E layer has on propagation that was detected over Eureka July 11, 2012. We event using receiver measurements path intersecting layer, simultaneous ionosonde series ray traces through model ionosphere containing layer. Utilizing these simulations, show how can aid some cases, simple Gaussian replicate real measurements. also comment could affect operation.
