Abstract. We report long-term observations of atmospheric parameters in the mesosphere and lower thermosphere (MLT) made over the last two decades. Within this study, we show based on meteor wind measurement, the long-term variability of winds, tides, and kinetic energy of planetary and gravity waves. These measurements were done between the years 2002 and 2018 for the high latitude location of Andenes (69.3° N, 16° E) and the mid-latitude locations of Juliusruh (54.6° N, 13.4° E) and Tavistock (43.3° N, 80.8° W). While the climatologies for each location show a similar pattern, the locations differ strongly with respect to altitude and season of several parameters. Our results show annual wind tendencies for Andenes which are toward the south-west, with changes of up to 3 m/s per decade, while the mid-latitude locations showing smaller opposite tendencies to negligible changes. The diurnal and semidiurnal tides also show different results for each location. Furthermore, the kinetic energy for planetary waves showed strong peak values during winters which also featured the occurrence of sudden stratospheric warming. The influence of the 11-year solar cycle on the winds and tides is presented.

Short summary
We report long-term observations of atmospheric parameters in the mesosphere and lower thermosphere made over the last two decades, for the northern latitude locations of Andenes, Juliusruh and Tavistock. The observations are based on meteor wind measurements and further include the long-term variability of winds, tides and the kinetic energy of gravity waves and planetary waves. While climatologies show a similar pattern, does seasonal tendencies differ strongly regarding location and altitude.
