We present the temperature database for the mesopause region, which was collected from spectral measurements of bands O2(0-1) and OH(6-2) with the infrared spectrograph SP-50 at the Maimaga station (63° N; 129.5° E) in 2002–2014. The temperature time series covers 11-year solar cycle. It is compared with the temperature obtained with the Sounding of the At-mosphere using Broadband Emission Radiometry in-strument (SABER, v.1.07 and v.2.0), installed onboard the TIMED satellite. We compare temperatures meas-ured during satellite passes at distances under 500 km from the intersection of the spectrograph sighting line with the hydroxyl emitting layer (~87 km) and oxygen emitting layer (~95 km). The time criterion is 30 min. We observe that there is a seasonal dependence of the difference between the ground-based and satellite measurements. The data obtained using SABER v2.0 show good agreement with the temperatures measured with the infrared digital spectrograph. The analysis we carried out allows us to conclude that a series of rotational temperatures obtained at the Maimaga station can be used to study temperature variations on different time scales including long-term trends at the mesopause height

INTRODUCTION
At present, the comparison between ground and satellite measurements is of topical interest. It is necessary to evaluate possible differences between them for a long period. We compare OH(6-2) and O2(0-1) rotational temperatures measured during 2002–2014 (the Maimaga high-latitude station (63° N; 129.5° E) infrared spectrograph) with mesopause kinetic temperatures at ~87 and ~95 km heights measured with the Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) instrument onboard NASA’s TIMED (Thermosphere, Ionosphere, Mesosphere Energetics and Dynamics) spacecraft [Mertens et al., 2001]. Many studies on the comparison between SABER temperatures and those measured with ground-based techniques and instruments have been published in recent years [Remsberg et al., 2008; Smith et al., 2010; French, Mulligan, 2010; Gavrilyeva et al., 2011]. They give an estimate of the offset or bias between data from SABER and ground-based instruments. All of these studies involve relatively short data runs [French and Mulligan, 2010]. We use ground-based data on OH(6-2) and O2(0-1) rotational temperatures for 2002–2014, which allow us to examine biases between SABER and Maimaga data obtained over this period.
