Statistical study about the influence of particle precipitation on mesosphere summer echoes in polar latitudes during July 2013
Abstract 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, pa...
