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

该项目的目标是展示用于专用航空学研究的地面、高分辨率、高通量便携式光谱仪的功能。紧凑的航空研究梯队光谱仪（CESAR）是由SRI国际在NSF的支持下建造的，可以提供最高分辨率的宽带光谱。通过这个项目，CESAR将在广泛的光谱范围内同时收集数据，并对可能相隔数百纳米的光谱特征之间的关系进行航空学研究。该系统被设计成在所有黑夜都可以远程操作。CESAR最初位于Poker Flat，将与Poker Flat非相干散射雷达（PFISR）位于同一位置，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.
