Polar mesospheric summer echoes (PMSE) often show different layers. Artificial electron heating experiments are an important diagnostic tool to investigate the parameters in the PMSE regions. The response of PMSE to high frequency heating in the lower (80–85 km) and upper (85–90 km) PMSE layers is studied by analyzing PMSE observations carried out by the EISCAT VHF radar in July 2007. Different characteristics...
Based on experimental observations with EISCAT VHF radar during the summer period, July 8–12, 2013, the observations of polar mesosphere summer echoes (PMSE) in the absence of particle precipitation indicate that particle precipitation is not a necessary condition for PMSE to exist. But, particle precipitation still affects PMSE when they both occur simultaneously. So in this paper, the relationship...
From EISCAT VHF radar observations it is evident that polar mesosphere summer echoes (PMSE) often show obvious layers. PMSE overshoot describe the effect of dusty plasma parameters on overshoot characteristics curve. In this paper we obtain and compare different PMSE overshoot characteristic curves (OCCs) at 80–85km and 85–90km in one hour respectively, from based on the data observed by EISCAT 224...
