Utilization of GPM Satellite and PERSIANN Satellite Data for Estimated Monthly Rainfall in South Sumatera
نویسندگان
چکیده
Rainfall data are widely used to predict regional rainfall. Limited rainfall is a problem that has an impact on decreasing accuracy, one of which in the area South Sumatra. This can be overcome by using satellites. However, utilize satellitebased data, it necessary carry out analysis determine accuracy data. research aims evaluate from GPM satellite and PERSIANN with validation calibration so value Satellite close measurement result estimate monthly In this study, were measured field, GPM, obtained 9 Sumatra districts for 2019 until 2021. The method was validated correlation coefficient, Root Mean Square Error (RMSE), Absolute (MAE). Calibration done combination method, solver algorithm Microsoft Excel, manually. estimated carried isohyet IDW interpolation method. results based showing closer field measurements than satellite. Based been calibrated, Region

TRMM satellite rainfall data
Spatial rainfall is a key input to Distributed Hydrological Models, which is the most important limitation for the accuracy of hydrological models. Model performance and uncertainty could increase when rain gauge is sparse. Satellite-based precipitation products would be an alternative to ground-based rainfall estimates in present and 5 the foreseeable future, however, it is necessary to evalua...
متن کاملThe Estimation of Monthly Rainfall from Satellite Da
The global distribution of precipitation is an outstanding example of a pattern whose form cannot be deduced very satisfactorily from conventional observational data. Many investigations of the global hydrological cycle across real periods of time are based on broadly generalized assumptions concerning rainfall patterns, especially over the world’s oceans. This paper explores the feasibility of...
