特殊传感器紫外线临边成像仪（SSULI）仪器是美国空军国防气象卫星计划Block 5D-3卫星上的紫外线临边扫描传感器。SSULI覆盖800-1700 nm波长范围，光谱分辨率为18 nm。这一波长范围包含了热层和F区电离层中所有主要中性和电离物质的光谱特征。这些仪器在航天器前方观察，并作为肢体成像仪工作，覆盖100-750公里的高度范围，分辨率为10-15公里，扫描节奏为90秒。我们描述了这些仪器，并总结了它们的校准和在轨性能。突出显示了低纬度夜间电离层的逐日变化和全球平均外逸层温度的长期变化。
The Special Sensor Ultraviolet Limb Imager (SSULI) instruments are ultraviolet limb scanning sensors flying on the United States Air Force Defense Meteorological Satellite Program Block 5D‐3 satellites. The SSULIs cover the 800–1700 Å wavelength range at 18 Å spectral resolution. This wavelength range contains spectral signatures of all the dominant neutral and ionized species in the thermosphere and F region ionosphere. The instruments view ahead of the spacecraft and operate as limb imagers covering the 100–750 km altitude range at 10–15 km resolution with a 90 s scan cadence. We describe these instruments and summarize their calibration and on‐orbit performance. Day‐to‐day variability of the nighttime ionosphere at low latitudes and longer‐term variability of the global mean exospheric temperature are highlighted.
