On the Retrieval Errors of Ultraviolet Back-Scattered Radiation Measuring Total Ozone

Now total atmospheric ozone amount derivation from the solar ultraviolet radiation backscattered from Earth measured by satellite has been one of the main methods to obtain total ozone amount data. Based on simulating calculation results, the paper studies and discusses the parameters which would influence the retrieval of total ozone amount arising from instrument errors and academic calculation errors, then quantificationally calculates the retrieval errors of total ozone amount induced by atmospheric radiative transfer model calculation errors, retrieval algorithm errors and instrument errors. The results obtained are very important for the precision improvement of total ozone amount retrieval and are directive for the disposal of the true datum obtained from FY-3A total ozone unit(FY-3A TOU) in the future.
