利用瑞利激光雷达在大气成分变化探测网（Network for the Detection of Atmospheric Composition Change）内北方三个不同纬度获得的长期温度廓线数据集，推导了中层大气温度趋势和对11年太阳活动周期的响应。激光雷达位于夏威夷的莫纳罗亚天文台（MLO，19.5°N）、加州的桌山设施（Table Mountain Facility，34.4°N）和法国的上普罗旺斯天文台（OHP，43.9°N）。平流层冷却趋势为2-3 K/decade，在MLO发现≤0.5 ± 0.5 K/decade。在中间层，在OHP（3-4 K/decade）的趋势比OHP和MLO（<1 K/decade）的趋势大得多。激光雷达的趋势与早期的卫星和火箭探空仪在平流层的趋势一致，但在中间层发现了很大的差异。1981-1994年OHP平流层上部的冷却趋势（0.2 -3 K/decade）远大于1995-2009年（≤0.8 K/decade），这与1995年后平流层上部臭氧密度略有增加相一致。结果表明，平流层和中间层的温度对11年太阳活动周期有显著的响应，在MLO和MLO时，两者的相关性均为正。1981-1994年期间，OHP在平流层上部观察到冬季负响应，在中间层中部观察到正响应，但在1995-2009年期间发现了相反的行为。这种行为可能根本不是直接的太阳周期响应，但可能与对十年变化的明显响应有关（例如，火山，调制随机发生的突然平流层变暖），这是更复杂的。
The long-term temperature profile data sets obtained by Rayleigh lidars at three different northern latitudes within the Network for the Detection of Atmospheric Composition Change were used to derive the middle atmosphere temperature trend and response to the 11 year solar cycle. The lidars were located at the Mauna Loa Observatory, Hawaii (MLO, 19.5°N); the Table Mountain Facility, California (TMF, 34.4°N); and the Observatoire de Haute Provence, France (OHP, 43.9°N). A stratospheric cooling trend of 2-3 K/decade was found for both TMF and OHP, and a trend of ≤0.5 ± 0.5 K/decade was found at MLO. In the mesosphere, the trend at TMF (3-4 K/decade) was much larger than that at both OHP and MLO (<1 K/decade). The lidar trends agree well with earlier satellite and rocketsonde trends in the stratosphere, but a substantial discrepancy was found in the mesosphere. The cooling trend in the upper stratosphere at OHP during 1981-1994 (∼2-3 K/decade) was much larger than that during 1995-2009 (≤0.8 K/decade), coincident with the slightly increasing upper stratospheric ozone density after 1995. Significant temperature response to the 11 year solar cycle was found. The correlation was positive in both the stratosphere and mesosphere at MLO and TMF. At OHP a wintertime negative response in the upper stratosphere and a positive response in the middle mesosphere were observed during 1981-1994, but the opposite behavior was found during 1995-2009. This behavior may not be a direct solar cycle response at all but is likely related to an apparent response to decadal variability (e.g., volcanoes, modulated random occurrence of sudden stratospheric warmings) that is more complex.
