The first 18 months of data from the FY-3A Total Ozone Unit (FY-3A/TOU) was collected to analyse instrument performance. Retrieval tests were carried out using post-launch calibration coefficients. Validation was analysed at 74 ground-based stations of total ozone network by inter-comparison with AURA/Ozone Monitoring Instrument (OMI) Total Ozone Mapping Spectrometer (TOMS) V8 data and comparison with ground-based measurements. The validation results show that the TOU total column ozone has an average root mean square (rms) error of less than 3.1% compared with OMI products, and less than 4.4% compared with ground-based measurements. The solar irradiance is measured continuously, and the post-launch calibration coefficients will be updated only if the change of instrument sensitivity has noticeable influence on the retrieval. The instrument is currently stable. [ABSTRACT FROM PUBLISHER]
