Statistical Characteristics and Mechanisms of Digisonde Echo Disappearances During Geomagnetic Storms

Journal of Geophysical Research: Space Physics
Abstract Geomagnetic storms, through the complex modulation of space weather, can disrupt observational instruments. During certain storms, digisonde observations exhibit complete echo disappearances, a phenomenon that has not been systematically investigated. We conducted a statistical analysis of this phenomenon using digisonde data

Thermospheric Neutral Wind Measurement Using the LWA1 and the AFRL Digisonde

2014
Abstract : We use the first station of the Long Wavelength Array (LWA1) to observe low power echoes from meteors due to illumination of meteor trails from TV or VHF radar. We built and deployed 5 Data Recorder Storage Units (DRSUs) at LWA1 and use these to collect data from the LWA1.
