The temporal change in height of a specific electron density can be used as a proxy for vertical plasma drift (PVPD) at the magnetic equator. The use of PVPDs as a predictor of low‐latitude ionospheric scintillation during the subsequent evening has previously been shown to have forecasting skill when using ionosonde data. The implementation of thi...
Conference Paper
We have proposed a high frequency (HF) over the horizon radar (OTHR) architecture with multiple receiving systems which are small and, therefore, relocatable. This Multistatic OTHR (MOTHR) configuration is based on a beamforming on transmit concept, with a very large aperture transmit antenna and a small aperture receive antenna. One consequence of...
Conference Paper
A proxy for vertical plasma drift (PVPD) at the magnetic equator can be used as an indicator of whether strong ionospheric scintillation will occur at low-latitudes. Using this approach with a physics-based model has previously been shown to demonstrate forecasting skill. AENeAS is an ensemble data assimilation model with a physics-based background...
Conference Paper
Determining the rate of change of the virtual height associated with a specific ionosonde frequency provides a proxy for vertical plasma drift (PVPD). Anderson et al. (2004) demonstrated that PVPDs at a location on the magnetic equator between 1830 and 2000 local time (LT) can be used as an indicator for the occurrence of low-latitude ionospheric s...
Conference Paper
Radio transmissions which pass through or are refracted by the ionosphere (e.g. GPS, HF communications) are critical for a number of civil and military systems. In low latitude regions ionospheric bubbles or plumes of depleted plasma can form after sunset. Transmissions passing through these plasma irregularities are subject to interference caused...
Conference Paper
The Advanced Ensemble electron density (Ne) Assimilation System (AENeAS) is an ensemble Kalman filter (EnKF) data assimilation model which uses the Thermosphere Ionosphere Electrodynamics General Circulation Model (TIE-GCM) as its background model. A successful EnKF model requires its ensemble members to span all possible observations. An ensemble...
