The PI continues his study of Polar Summer Mesospheric Echoes with a new twist: exploring the aeronomy. Using data acquired by the MST radar at the Early Polar Cap Observatory, a post-doc: (1) looks for interrelationships between spectral widths and signal-to-noise, and the phase of any present oscillations, (2) compares the scattering properties with the meteor diffusion times to locate a Schmidt Number effect in the latter (if it exists), and (3) uses the wave dispersion relationship to discover the high frequency limit to which meteor temperatures can be pushed by comparing them to wind perturbations measured with the radar. Further, the PI remains committed to exploring Canadian instrumentation's data as a marker for global change (as manifested in the mesosphere).

首席研究员以新的方式继续他对极地夏季中层回声的研究：探索航空学。 使用早期极冠天文台的 MST 雷达获取的数据，博士后：(1) 寻找频谱宽度和信噪比以及任何当前振荡的相位之间的相互关系，(2) 将散射特性与流星扩散时间进行比较，以定位后者中的施密特数效应（如果存在），以及 (3) 使用波色散关系来发现高频极限 通过将流星温度与雷达测量的风扰动进行比较，可以推算流星温度。 此外，PI 仍致力于探索加拿大仪器数据作为全球变化的标记（如中间层所示）。
