Plasma convection at high latitudes using the EISCAT VHF and ESR incoherent scatter radars
International audience The recent availability of substantial data sets taken by the EISCAT Svalbard Radar allows several important tests to be made on the determination of convection patterns from incoherent scatter radar results. During one 30-h period, the Svalbard Radar made 15 min scans combini...
