CEDAR: Multi-Station Ground Based Observations of the Dynamics and Energetics of the Southern High and Mid-Latitude Upper Thermosphere

该项目旨在解释pi发现的地面法布里-佩罗测量的热层风与数值模型预测的风之间的差异。以前的研究将热层模型与单个地面台站、多个北半球台站有限时期的数据以及仅与DE-2航天器的太阳极大期数据进行了比较。然而，当使用南极纬度的多个法布里-珀罗光谱仪的数据时，pi寻求分歧的原因。在此过程中，他们将利用多个高纬度南半球站点，将之前的比较扩展到太阳极大期之外。联合研究的结果将在广泛的地球物理条件下对南极热层进行基于观测的描述。

This project seeks to explain discrepancies the PIs have found between ground-based Fabry-Perot measurements of thermospheric winds and those predicted by numerical models. Previous studies have compared thermospheric models with single ground-based stations, with data from limited periods using multiple northern hemisphere stations, and with DE-2 spacecraft data for solar maximum only. However, the PIs seek reasons for disagreement when using data from multiple Fabry-Perot spectrometers at southern polar latitudes. In doing so, they will extend previous comparisons away from solar maximum using multiple high latitude southern hemisphere sites. Results from the combined study will present an observation-based description of the southern polar thermosphere over a broad range of geophysical conditions.
