High Latitude Ionospheric Gradient Observation Results from a Multi-Scale Network

High latitude regions are known to frequently have increased ionospheric activity and observe smaller size of high-density irregularities. Observation of small spatial-scale ionospheric delay features is a challenge for sparse CORS networks. This presentation provides a summary of results obtained from analysing a full year of data collected by a multi-scale cluster of receivers located in a high latitude region (centred at about 69.5° N, 19° E) with regard to the ionospheric gradient characteristics and behaviour.
