The invention discloses a sparse region rainfall estimation fusion method based on a dual-smoothing method. On the basis of data assimilation thought, rainfall point data observed by rain gauges and TMPA grid rainfall data are integrated together to form a set of discrete points, finally, and the two integrated data sets are turned into an improved novel data set; meanwhile, smoothing is adopted for correcting discontinuity formed before TMPA fusion. According to the dual-smoothing method, rainfall values and spatial distribution are more reasonable and effective, average deviation and root-mean-square errors of a region where rain gauges are distributed sparsely change slightly along with time, heavy rainfall can be more accurately estimated, and meanwhile the rainfall visual result is smoother. The method is particularly applicable to regions where automatic meteorological stations are spatially distributed sparsely in a western region.
