• #### Study of meso-scale reversed flow events in the polar ionosphere by SuperDARN radars ﻿

(The University of Bergen, 2017-06-29)
In this study we have investigated Reversed Flow Events (RFEs) in the northern hemisphere polar cap. A RFE is an ∼50-250 km wide flow channel that opposes the large scale background flow. A total of 57 new RFEs were ...
