Halley MF (Medium Frequency) Radar

The MF radar measures an altitude profile of the horizontal wind in the mesosphere, between 55 and 95 km.

This is the region where breaking gravity waves drive a pole-to-pole circulation and where dynamics plays and important role in the coupling of the lower and upper atmosphere. The radar provides a measurement of gravity wave activity and detects atmospheric tides and planetary waves. The radar can also be used to provide an indication of the height of energetic charged particle precipitation.
