Time series of mesospheric temperature and pressure altitude are produced through combining observations by the Halogen Occultation Experiment (HALOE), Sounding of the Atmosphere Using Broadband Emission Radiometry (SABER), and Solar Occultation for Ice Experiment (SOFIE) instruments. Time series of both temperature and pressure altitude are produced through the combination of HALOE/SABER providing 29 years in length and HALOE/SOFIE providing 22 years in length. The different sampling of the three instruments constrains the time series to June in the northern hemisphere and December in the southern hemisphere and 64–70° in both hemispheres. We interpret the time series by fitting them to simple descriptions of the variations including solar, intra-hemispheric, inter-hemispheric, and linear trend terms. The inferred intra- and inter-hemispheric terms show that dynamical influences rival solar variability in the mesosphere. We find a robust result that the mesosphere is in general cooling at most altitudes at approximately 1–2 K per decade in response to greenhouse gas increases. That cooling leads to a shrinking of the atmosphere on the order of 100–200 m per decade. The shrinking leads to a reduction in cooling and eventually a warming near 0.005 hPa due to hydrostatic contraction.

中层温度和压力高度的时间序列是通过结合卤素掩星实验（HALOE），使用宽带发射辐射法测得的大气探测声（SABER）和冰太阳掩星实验（SOFIE）仪器的观测结果而得出的。温度和压力高度的时间序列是通过提供29年长度的HALOE / SABER和提供22年长度的HALOE / SOFIE组合而产生的。三种仪器的不同采样将时间序列限制在北半球的6月和南半球的12月以及两个半球的64–70°。我们通过使时间序列适合变化的简单描述来解释时间序列，包括太阳，半球内，半球间和线性趋势项。推断出的半球内和半球间术语表明，动力学影响了中球层中与之竞争的太阳的可变性。我们发现一个有力的结果是，随着温室气体的增加，中层大气在大多数高度普遍处于降温状态，每十年大约1-2K。这种冷却导致大气每十年收缩约100–200 m。收缩导致冷却降低，并由于静水收缩最终导致接近0.005 hPa的升温。
