Atmospheric temperature from AURA (MLS) satellite and OH (3-1) measurements in Maimaga

Results of the study of the temperature in the mesopause region (∼87 km) based on measurement of OH (3-1) emission at the high latitude station Maimaga (63.04° N, 129.51° E) are presented and compared with the Aura (MLS) measurements of temperature at 0.002 hPa in 2013–2018 when flying over the Maimaga station. The average rotational temperature of OH (3-1) was compared with temperatures measured by Aura (MLS) and the background temperatures calculated from them. The results show more correct comparison of the OH (3-1) temperature with the background temperature calculated from Aura (MLS) data. The comparison confirms the observation of high temperatures in the mesopause in winter 2014/2015. In general, the temperature variations measured by two different methods are qualitatively consistent and answer the seasonal variations. Temperature differences can be explained by many factors, e.g., differences in measuring altitudes and techniques.
