Detection of traveling ionospheric disturbances with auroral zone incoherent scatter radar

摘要

A technique for the study of traveling ionospheric disturbances has been developed using the incoherent scatter radar at Chatanika, Alaska. Using one wave event, the technique is employed to compute the period of oscillation (36.5 min), southward velocity (208 m sec), and power profile. A possible source event for the traveling ionospheric disturbance has been identified as being a filamentary auroral arc moving southward toward Chatanika.
