Fig. 2From: GPS and in situ Swarm observations of the equatorial plasma density irregularities in the topside ionosphereComparison of Swarm ROTI and RODI variations for the SWA ascending passes (~20.3 LT) on March 10, 2015. a ROTI values along all separated links Swarm-to-GPS; b RODI values along Swarm track; example of c ROTI and d RODI variation extracted from general maps, which marked by green narrow, and superimposed in situ Ne values as measured by the Swarm LP.
