Sub-auroral longitudinal anomalies in ionosphere-protonosphere system according to GSM TIP model and IK-19 satellite and ground-based observation

摘要

We studied the morphology of sub-auroral summer longitudinal anomalies, which includes Weddell Sea Anomaly (WSA) and Yakutsk Anomaly (YA). For this purpose, we used both IK-19 satellite and ground-based ionosonde data and GSM TIP model results. We also present WSA and YA manifestation in protonosphere.
