Assessment of gravity wave momentum flux measurement capabilities by meteor radars having different transmitter power and antenna configurations

This international collaboration demonstrated that meteor radars of different configurations nevertheless make inter-comparable measurements of the momentum fluxes of gravity waves in the mesosphere. These fluxes are a key driver of mesospheric global circulation and their determination is critical in constraining the development of Global Circulation Models. This result led to an award from NERC to deploy a meteor radar on South Georgia in the Southern Atlantic to measure these fluxes over that island as part of the £1.2M South Georgia Wave Experiment (SG-WEX) project (overall PI, NJ Mitchell, Bath’s share FEC £549k, NE/K015117/1). The work is interdisciplinary with physics.
