极地夏季中间层顶附近的冰粒可通过目测、雷达和各种远程和原位技术进行观测。本研究研究了ALOMAR风雷达（ALWIN）的同步雷达观测和Mesosphere冰学卫星（AIM）上的掩星冰实验（SOFIE）的测量结果。从雷达观测到的中间层冰被称为极地中间层夏季回波（PMSE），而这些粒子的卫星观测被称为极地中间层云（PMC）。SOFIE和ALWIN同步观测结果的比较表明，PMC和PMSE是同一层的不同表现。ALWIN和SOFIE记录的冰盖垂直范围相似，主要区别在于PMSE信号的峰值比PMC信号高约2km。SOFIE对冰颗粒大小和浓度的观测用于验证PMSE的简单经验代理，这些代理先前是基于少量火箭观测和微物理模拟提出的。
Ice particles near the polar summer mesopause are observed visually, by radar, and using various remote and in-situ techniques. This study investigates concurrent radar observations from the ALOMAR wind (ALWIN) radar and measurements from the Solar Occultation For Ice Experiment (SOFIE) onboard the Aeronomy of Ice in the Mesosphere (AIM) satellite. Mesospheric ice observations from radar are known as polar mesosphere summer echoes (PMSE), while satellite observations of these particles are referred to as polar mesospheric clouds (PMC). Comparisons of concurrent SOFIE and ALWIN observations indicate that PMC and PMSE are different manifestations of the same ice layer. The vertical extent of the ice layer is similar in the ALWIN and SOFIE records, with the primary difference that the PMSE signal peaks about 2km higher than the PMC signal. SOFIE observations of ice particle size and concentration are used to test simple empirical proxies for PMSE which have previously been suggested based on a small number of rocket observations and microphysical modeling.
