FY-3A气象卫星紫外臭氧垂直探测仪

Ultrariolet Ozone Vertical Profile Probe for FY-3A Meteorological Satellite

研制成FY-3A气象卫星紫外臭氧垂直探测仪,于2008年5月发射。它是一台小型化、高精度、紫外-真空紫外光谱辐射计,用于测量大气太阳后向散射光谱辐亮度和太阳光谱辐照度,通过数据反演得到大气臭氧总量的垂直分布。在轨道高度830 km处获得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及太阳后向散射谱,在轨测试结果表明:FY-3A气象卫星紫外臭氧垂直探测仪全部功能正常,性能稳定。

Ultraviolet ozone vertical profile probe for FY-3A meteorologic satellite was developed and launched successfully in May 2008. It is a compact, high-precision, ultraviolet-vacuum ultraviolet spctroradiometer used to measure atmospheric solar backscattering spectral radiance and solar spectral irradiance. The solar spectral irradiance at altitude 830 km in 160- 400 nm and the hackscatterion solar spectral radiance in the ultraviolet ozone absorption band at 12 wavelengths from 250 nm to 340 nm are obtained. Test results on orbit show that all the function is carried out successfully and the performance is stable.
