The OMPS Limb Profiler instrument An alternative data analysis and retrieval algorithm

摘要

An alternative algorithm is being analyzed to retrieve ozone and aerosol vertical distribution information from the OMPS/LP sensor which will be manifested on the upcoming NPOESS Preparatory Project (NPP) platform in early 2011. The algorithm relies on the optimal estimation method to infer ozone density and aerosol extinction directly from the radiance measurements made by the ensemble of CCD array pixels. The fundamentals of the technique are reviewed and the advantages of the method with respect to the mainstream retrieval algorithm are discussed. Sample results are given to illustrate the performance of the new method.
