Rainfall has direct impact on life and economy of the people in an agricultural country like Afghanistan. High amount of rainfall causes floods and as a result of that, destruction of houses and agricultural lands and low rainfall causes drought and loss of plants. Measurement of rainfall in a water zone is very important for studying of water cycle, water management, floods identification, agricultural activities and etc. Due to economic and security problems in Afghanistan, there are no enough hydrological stations to measure the rainfall in the most parts of the country. Despite, most of the rainfall data from existing stations is not available from the years 1980 to 2008. Also, the data of the hydrological stations are not readily available publicly. Fortunately, with the advancement of science and technology, today there are several satellites that can accurately record information on rainfall and other atmospheric processes. Data from remote sensing method is freely available and easily accessible to everyone in the world. In this study, the accuracy and reliability of the Climate Hazards Group InfraRed Precipitation with Station Data (CHIRPS) has been investigated and further research has been done to investigate the cause of the errors in order to minimize the difference between satellite estimation and observed rainfall data in hydrological stations. As a result, it was found that there is a good relationship between the rainfall data that estimated by CHIRPS and the rainfall data from hydrological stations at monthly level in the Harrirod-Morghab river basin; but precipitation that has obtained from CHIRPS is slightly higher than obtained data from hydrological stations.
