抽象。2010年11月19日至12月19日，在挪威北方的Andoya火箭靶场（北纬69度，东经16度）进行了第四次也是最后一次ECOMA火箭发射活动。我们提出并讨论了在最后一次火箭发射ECOMA09时，同时和真正的共同体积的温度和湍流的地面激光雷达观测支持原位测量结果显示两个中间层逆温层（MIL）在71和73公里之间的高度和86和89公里之间。在上部逆温层区域测得强湍流，湍流能量耗散率在2 W kg−1时最大。ALOMAR Weber Na激光雷达在几个小时的时间内观察到了这个上部MIL。AURA卫星上的MLS仪器观测到的这一MIL的空间延伸超过2000公里。我们的分析表明，这两个观察到的MIL可能是由中性空气湍流产生的。
Abstract. From 19 November to 19 December 2010 the fourth and final ECOMA rocket campaign was conducted at Andoya Rocket Range (69° N, 16° E) in northern Norway. We present and discuss measurement results obtained during the last rocket launch labelled ECOMA09 when simultaneous and true common volume in situ measurements of temperature and turbulence supported by ground-based lidar observations reveal two Mesospheric Inversion Layers (MIL) at heights between 71 and 73 km and between 86 and 89 km. Strong turbulence was measured in the region of the upper inversion layer, with the turbulent energy dissipation rates maximising at 2 W kg−1. This upper MIL was observed by the ALOMAR Weber Na lidar over the period of several hours. The spatial extension of this MIL as observed by the MLS instrument onboard AURA satellite was found to be more than two thousand kilometres. Our analysis suggests that both observed MILs could possibly have been produced by neutral air turbulence.
