SOUSY Svalbard Radar

Used for troposphere and mesosphere research and located in Adventdalen near Longyearbyen on Svalbard. The radar monitors the height of the tropopause - interesting for climate change studies - and the state of the mesosphere, in particular strong echoes during summer - so-called PMSE

The realtime webcam view is across Adventdalen to the north, with part of the SOUSY antenna array - 356 elements in all - in the foreground.

Current mesosphere data

The persistent echoes between 80 and 90 km altitude are so-called "PMSE" and occur only in summer.
Isolated echoes around 90 km altitude can be meteors.

Current troposphere data

A persistent layer between 10 and 12 km altitude shows the tropopause - the demarcation between troposphere and stratosphere. Echoes above 12 km are probably artifacts of PMSE from higher up. Structures in the region below 8 km can be waves, turbulence and fronts
