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 backscatterion 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.
