CEDAR: Studies with Compact Echelle Spectrograph for Aeronomical Research (CESAR)

该项目的目标是展示地面、高分辨率、高通量便携式光谱仪的功能，用于专门的空气动力学调查。用于大气研究的紧凑型回声光谱仪(CESAR)是由SRI国际在美国国家科学基金会的事先支持下建造的，以提供最好的分辨率宽带光谱。通过这个项目，CESAR将在广泛的光谱范围内收集同步数据，并能够对可能相隔数百纳米的光谱特征之间的关系进行空气动力学调查。该系统被设计为在所有黑夜都可以远程操作。塞萨尔最初设在扑克坪，将与扑克坪非相干散射雷达(PFISR)共处一处，PFISR是一种由NSF资助、SRI操作的相控阵非相干散射雷达。

The goal of this project is to demonstrate the functionality of a ground-based, high-resolution, high-throughput portable spectrograph for dedicated aeronomic investigations. The Compact Echelle Spectrograph for Aeronomical Research (CESAR) was constructed by SRI International with prior support from NSF to provide the finest-resolution wide-bandwidth spectra. Through this project, CESAR will collect simultaneous data over a broad spectral range and enable aeronomic investigations about relationships between spectral features that may be separated by hundreds of nanometers. The system is designed to be operated remotely during all dark nights. Initially sited at Poker Flat, CESAR will be co-located with Poker Flat Incoherent Scatter Radar (PFISR)--an NSF-funded, SRI-operated, phased-array incoherent scatter radar.
