AB: The campaign, Mountain and Convective Waves Ascending Vertically (MaCWAVE) took place during the summer from the Andoya Rocket Range in Norway and during the winter from ESRANGE in Sweden. The purpose of MaCWAVE was to determine the morphology of gravity waves and their generation from convection during the summer and mountain wave activity during the winter. MaCWAVE included a large number of meteorological rockets comprised of 26 inflatable falling sphere flights during the summer campaign and 46 flights during the winter campaign. Temperature and wind data to approximately 90 km show summer mesospheric structure having very similar profiles although evidence of a diurnal cycle is apparent. However, the winter mesospheric structure is quite variable. Identifying mountain wave propagation of gravity waves is difficult due to easterly winds from a stratospheric warming inhibiting westerly flow over the mountains. In situ and remote observations obtained during similar time periods are examined for similarities and differences. Time series, while limited over time, show the cyclic nature of the mesospheric temperature and wind data.
