There has been much discussion as to the veracity of neutral wind measurements made using medium‐frequency radar (MFR) employing the spaced‐antenna technique. Such systems are able to operate continuously, providing information on mesosphere and lower thermosphere dynamics with typical resolutions of 3 km in altitude and 5 min in time, and thus represent a low‐cost monitoring of the atmosphere. It is similarly important to be able to trust the results, and therefore we make a dedicated comparison between the Tromsø MFR (70°N, 19°E) and the newly installed and colocated Nippon/Norway Tromsø meteor radar. The agreement is particularly good between 75 and 85 km.
