From the 14 th of November to the 21 st of November 1999 measurements of the upper mesospheric temperatures were performed on Svalbard (78°N, 16°E). Both the SOUSY Svalbard Radar and a one meter focal length Ebert‐Fastie spectrometer were used, the first instrument measured the decay and phase changes of meteor echoes, and the latter measured the OH(6–2) rotational spectrum. These allowed us to deduce themperature estimates at 80–90 km altitude. Due to the differences in the height of the measurements the temperatures were compared on the background of the temperature profile according to the COSPAR International Reference Atmosphere and reasonable agreement was found.
