A Regional Network of TID Sensors: NTIDS
Abstract
In this effort we propose to acquire a distributed sensor to monitor dynamic variations in theelectron density of the upper atmosphere known as traveling ionospheric disturbances, or TIDs.TIDs generally affect radio wave propagation and specifically cause major changes in the directionof high frequency (HF) signals used for communication and surveillance systems. In fact,depending on the specifics of the application, TIDs may represent the limiting factor in systemperformance. Scientifically they are important because most TIDs are the ionospheric signaturesof waves propagating in the neutral atmosphere, potentially originating in the tropospheregenerated by terrestrial weather activity or natural hazards such as earthquakes and tsunamis.These neutral waves, known as acoustic gravity waves (AGWs), effectively transfer momentumin the atmosphere, impact weather systems and represent an important coupling mechanismbetween diverse regions of the atmosphere. The sensor system proposed here is designed tomeasure regional TID parameters to better understand TID generation and propagation, facilitatingthe development of a predictive TID model.
