dc.description.abstract Beamfilling error is one of the main error sources for microwave oceanic rainfall retrieval . An accurate beamfilling correction can improve the rainfall retrieval accuracy significantly . Quantitative understanding of the uncertainty of the Beamfilling Correction Factor (BCF ) is very important for the understanding of the accuracy of microwave passive rainfall retrieval . Refinement of the calculation of the BCF and the estimation of BCF uncertainty are the main purposes of this thesis . The characteristic of rainfall distribution is investigated . Quantitative understanding of the statistical characteristics of rainfall distribution provides an indication of the beamfilling error and the uncertainty of BCF in many ways . Some refinements to the traditional BCF calculation algorithm are provided in this thesis . Scattering is included in the new algorithm . Also the BCF calculation only considers the cases within the useful dynamic range . These refinements make the BCF calculation closer to how it is used in the retrieval algorithm . The BCF based on the new algorithm should be more accurate . The global BCF uncertainty and the local BCF uncertainty are estimated using the available A /C radar data . The results show that the uncertainty of BCF is much smaller than expected , and also show that the BCF derived from a specific set of data can be used globally . en_US
