| 摘 要： | 介绍了国内外星载太阳紫外光谱辐射计的研究进展,对我国自行研制的星载臭氧垂直探测仪的结构和功能进行了简介。它是一种小型化、高精度的紫外-真空紫外光谱辐射计,可在轨测量获得160～400nm地外太阳绝对光谱。给出了星载臭氧垂直探测仪实测的地外太阳紫外光谱并对其精度进行了分析。误差分析表明,160～250nm地外太阳绝对光谱的测量不确定度为±6.4%;250～400nm为±5.2%。将臭氧垂直探测仪在轨观测结果与国际同类仪器进行了比对,一致性优于±5%。

| Abstract: | The study process of the satellite-borne solar ultraviolet spectrometer is briefly introduced.The optical and mechanical structures of the ultraviolet spectrometer(SBUS) are introduced.SBUS is a compact,high-precision satellite-borne spectral radiometer.It can measure 160~400 nm solar ultraviolet-spectral irradiance under solar work modes.The calculation method and uncertainty factors of the measured ultraviolet spectral irradiance are analyzed.The measurement uncertainty analysis shows that the total uncertainty of the measured ultraviolet spectral irradiance is ±6.4% at 160~250 nm and ±5.2% at 250~400 nm.The data of solar ultraviolet spectral irradiance obtained by SBUS agree with the internationally published data with the deviation within ±5%. |
