Summary:The invention discloses a rainfall data optimization method, device and equipment for a data-deficient area and a storage medium, and the method comprises the steps: obtaining a satellite daily rainfall sequence of an actual measurement site of the data-deficient area, carrying out the statistics of rainfall, rainy day frequency and rainfall probability distribution from the satellite daily rainfall sequence, and carrying out the deviation correction of the satellite daily rainfall sequence, performing daily scale fusion on the corrected rainfall sequence of each actual measurement site to obtain daily scale fusion rainfall data, constructing a random forest model through the daily scale fusion rainfall data, and training the random forest model in combination with multiple land coverage types to obtain a rainfall link model; and finally, inputting the high-resolution auxiliary factors into the rainfall link model, and outputting high-spatial-resolution rainfall data. Therefore, satellite precipitation and gr
