Polar mesospheric summer echoes (PMSE) have been studied with radar and in-situ probes since more than 20 years and their existence is well understood. On-going efforts are devoted to use them as tracers of the background dynamics and to understand their spatial and temporal evolution. Recently, Sommer and Chau [2016] has shown, using aperture synthesis radar imaging, that scattering from irregularities associated to PMSE is mainly isotropic and they are mainly organized in patches smaller than 5 km in horizontal extension (i.e., smaller than typical illuminated areas). To further validate this finding, common volume observations with different observing angles are needed. In this work we present preliminary results of such measurements, using MAARSY (Middle Atmosphere Alomar Radar System) and KAIRA (Kilpisjärvi Atmospheric Imaging Receiver Array). KAIRA is a radio receiver array (Low-frequency Array - LOFAR) with one of its arrays operating in the 10 to 80 MHz VHF band. Our results are based on a campaign conducted in August 2016. Besides using MAARSY for transmission and reception (at 53.5 MHz), we have also used the Andenes specular meteor radar for transmission and reception (at 32.55 MHz). Both frequencies were received simultaneously at KAIRA, located approximately 190 km east from MAARSY. We also present results from different frequencies and different locations using these multi-static configurations. Our multi-angle results indicate that indeed PMSE is not as aspect sensitive as previously thought.
