Accurate acquisition of land water reserve changes has important scientific significance and social and economic benefits for analyzing the spatial and temporal distribution characteristics of regional water reserve changes, understanding large and medium-scale hydrological processes, studying water resources changes and effective management, and predicting drought and flood disasters. Water is strange, is life. The objective of this study is to have the variation of water resulting from different seasons. In fact, given that we are using the map directly, we have realized that there are strip errors and noises which means that we cannot accurately determine the variation of water storage in different seasonal .For this reason, we use the Gaussian method to correct the errors and the noise to be able to analyze and compare with precision the focuses on the spatial filtering method, analyses and compares the filtering effects of different filtering methods, and chooses the Central African Republic as the experimental area to analyze the variation law of terrestrial water reserves in this area over the years, and to explore the origin of its generation also the method for improving the accuracy of estimation of terrestrial water reserves by combining GRACE data and GLDAS data to use GRACE'S land water reserve data and GLDAS model from 2003 to 2016 to simulate soil water content data, and to calculate the change of the variations water storage in this area.
