A semisimultaneous inversion algorithm for SAGE III

摘要: [1] The Stratospheric Aerosol and Gas Experiment (SAGE) III instrument was successfully launched into orbit on 10 December 2001. The planned operational species separation inversion algorithm will utilize a stepwise retrieval strategy. This paper presents an alternative, semisimultaneous that simultaneously retrieves all over user-specified vertical intervals or blocks. By overlapping these blocks, retrieved profiles the entire range of measurements are obtained. approach provides more straightforward method for evaluating error coupling occurs among due to various types input uncertainty. Simulation results presented show how can enhance understanding SAGE process. In future, be used help evaluate performance inversion. Compared II, provide expanded precise spectral measurements. alone is shown significantly reduce uncertainties in ozone, nitrogen dioxide, aerosol extinction III. Additionally, well-documented concern II retrievals biased by level volcanic greatly alleviated
