介绍了我国自主研制的用于地外太阳紫外光谱测量的FY-3紫外臭氧垂直探测仪，利用该仪器成功获得了地外太阳紫外光谱数据。该紫外臭氧垂直探测仪是一台结构紧凑，工作波段为160~400 nm的紫外-真空紫外光谱辐射仪。报导了该探测仪的组成和工作原理，描述了它的3种工作模式，即大气模式、太阳模式和标准灯模式。介绍了太阳模式下该探测仪的光谱辐照度定标，受光源性能所限，光谱辐照度定标分160~300 nm 和250~400 nm两个波段进行。最后，给出了利用紫外臭氧垂直探测仪获得的太阳紫外光谱和数据处理结果。结果表明，利用该探测仪在轨获得的160~400 nm太阳连续光谱和250~340 nm间 12个特征波长的太阳分立光谱与美国SBUV/2获得的测量数据的一致性在±5%以内。

The Ultraviolet Ozone Vertical Profile Probe (UOVPP) on FY-3A meteorological satellite developed by our country is introduced for measuring the extraterrestrial solar ultraviolet spectra, and the spectral irradiance data are obtained by the probe successfully.The UOVPP is a compact UV-VUV spectral radiometer worked at 160~400 nm.The composition and principle of the probe are reviewed and three kinds of working modes, namely, atmospheric mode, solar mode, and standard lamp mode, are described.Furthermore, the spectral irradiance calibration of the probe under the solar mode is introduced, which is carried out at 160~300 nm and 250~400 nm respectively owing to the limitation of source characteristics.Finally, the solar ultraviolet spectrum captured by the UOVPP and processed data are given.It is shown that the solar continuous spectrum at 160-400 nm and solar discrete spectrum of 12 characteristic wavelengths at 250-340 nm measured from UOVPP on orbit are in good agreement with those from SBUV/2, and their measurement uncertainty is within ±5%.
